# CannaManage — Local Docker Testing + Playwright E2E (with real tokens)
|
||||||
|
|
||||||
|
**From:** Homelab Lumen (Fedora workstation, Roo Code)
|
||||||
|
**To:** Work Lumen (Mac, Kiro IDE)
|
||||||
|
**Date:** 2026-06-13
|
||||||
|
**Topic:** How to test CannaManage with the local Docker stack on the Mac, why curl was not enough, what we found, and what extra Playwright tests need to be implemented — including how to wire real auth tokens.
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## TL;DR
|
||||||
|
|
||||||
|
We deployed CannaManage to the TrueNAS Docker stack and chased a string of "it loads but
|
||||||
|
nothing works" bugs. The decisive lesson:
|
||||||
|
|
||||||
|
> **`curl` validates the server. Only a real browser validates the app.**
|
||||||
|
> Many bugs only appear during **React hydration** or because **the browser never sends the
|
||||||
|
> auth token** that a hand-crafted `curl` does. We need automated Playwright E2E tests that
|
||||||
|
> drive a real browser through a real login and assert on real authenticated API calls.
|
||||||
|
|
||||||
|
This doc tells you how to run the stack locally on the Mac, what we found, and the concrete
|
||||||
|
Playwright suite to build.

||||||

|
||||||
|
|
||||||
|
## 1. Why local Docker testing on the Mac matters
|
||||||
|
|
||||||
|
- **Parity with prod.** The TrueNAS deploy runs the exact `docker-compose.yml` + frontend/backend
|
||||||
|
images. Running the same compose locally on the Mac reproduces prod-only bugs (SSG/hydration,
|
||||||
|
service worker, the Next.js rewrite proxy, NextAuth cookies) that `npm run dev` hides.
|
||||||
|
- **The proxy + auth chain only exists in the built app.** `next dev` and unit tests bypass the
|
||||||
|
`/api/backend/* → BACKEND_URL/api/v1/*` rewrite and the NextAuth session cookie flow. Bugs in
|
||||||
|
that chain (we hit several) are invisible until you run the real container.
|
||||||
|
- **curl lies by omission.** curl talks straight to the backend and *you* attach the `Authorization`
|
||||||
|
header by hand. The browser does NOT — see §3. So curl can return 200 on an endpoint that is
|
||||||
|
100% broken in the actual app.
|
||||||
|
|
||||||
|
### How to run it locally on the Mac
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# from the repo root
|
||||||
|
cd cannamanage
|
||||||
|
|
||||||
|
# Build + start the full stack (db + backend + frontend)
|
||||||
|
docker compose up -d --build
|
||||||
|
|
||||||
|
# Watch health
|
||||||
|
docker compose ps
|
||||||
|
docker compose logs -f backend # wait for "Started CannaManageApplication"
|
||||||
|
|
||||||
|
# App: http://localhost:3000 (frontend)
|
||||||
|
# API: http://localhost:8080 (backend) ← NOTE: on the Mac 8080 is free; see warning below
|
||||||
|
# DB : localhost:5432
|
||||||
|
|
||||||
|
# Seed the dev admin + data (after backend has run Flyway):
|
||||||
|
docker exec -i cannamanage-db psql -U cannamanage -d cannamanage < scripts/seed/init.sql
|
||||||
|
|
||||||
|
# Login creds (dev seed): admin@test.de / test123
|
||||||
|
```
|
||||||
|
|
||||||
|
> ⚠️ **Port warning (bit us hard on TrueNAS):** on the homelab server, host port **8080 was
|
||||||
|
> already taken by SearXNG**, so the backend was remapped to host **8081** (internal stays 8080,
|
||||||
|
> so `BACKEND_URL=http://backend:8080` is unchanged). On the Mac, 8080 is usually free — but
|
||||||
|
> **always confirm which port the backend is actually published on before you curl it.** I wasted
|
||||||
|
> a chunk of this session curling `:8080` and getting SearXNG's 404 page back, which looked like
|
||||||
|
> "all routes 404." Check `docker compose ps` / `docker compose port backend 8080`.

## 2. The tooling we added (so you can do the same)
|
||||||
|
|
||||||
|
On the Fedora workstation (no Node was installed!) we set up a **Playwright browser probe**:
|
||||||
|
|
||||||
|
- Installed Node 22 + npm, then `@playwright/mcp` + Chromium (`npx playwright install chromium`).
|
||||||
|
- Wrote a standalone probe script: [`cannamanage/scripts/debug/dashboard-probe.mjs`](../../cannamanage/scripts/debug/dashboard-probe.mjs)
|
||||||
|
It logs in through the real `/login` form and captures **console errors, pageerrors, failed
|
||||||
|
requests, and 4xx/5xx responses** + a screenshot. This is what exposed every client-side bug
|
||||||
|
that curl could not see.
|
||||||
|
|
||||||
|
On the Mac you already have Node, so just:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
cd cannamanage/scripts/debug
|
||||||
|
npm install playwright
|
||||||
|
npx playwright install chromium
|
||||||
|
BASE_URL=http://localhost:3000 LOGIN_EMAIL=admin@test.de LOGIN_PASSWORD=test123 node dashboard-probe.mjs
|
||||||
|
```
|
||||||
|
|
||||||
|
There is also a Playwright MCP server now (server name `playwright`) wired into Roo's
|
||||||
|
`mcp_settings.json` — gives `browser_navigate`, `browser_snapshot`, `browser_console_messages`,
|
||||||
|
`browser_network_requests`, `browser_take_screenshot` as tools. Worth adding to Kiro too.
|
||||||

## 3. What we found (the bug catalogue)
|
||||||
|
|
||||||
|
### A. App-wide hydration crash — the "Oops! Something went wrong" (FIXED, commit `4be9c4c`)
|
||||||
|
- Root `app/layout.tsx` rendered global client components (`PwaInstallPrompt` → `useTranslations`,
|
||||||
|
`Toaster`, `Sonner`) as **siblings of `{children}`**, but only each route-group layout wrapped
|
||||||
|
*its own* children in `NextIntlClientProvider`. Those globals had **no intl context** → next-intl
|
||||||
|
threw on **every page including `/login`** → React error boundary "Oops".
|
||||||
|
- **curl saw HTTP 200** for `/login` the whole time — because the crash is in client hydration.
|
||||||
|
- Fix: root layout is now `async` and wraps the body in `NextIntlClientProvider` via `getMessages()`.
|
||||||
|
|
||||||
|
### B. PWA assets caught by auth middleware (FIXED, commit `4be9c4c`)
|
||||||
|
- `middleware.ts` matcher didn't exclude `/manifest.json` or `/sw.js` → both 307'd to `/login`
|
||||||
|
(HTML). Browser parsed HTML as JSON (`manifest.json:1 Syntax error`) and a stale/HTML service
|
||||||
|
worker kept serving old bundles ("website hasn't changed after redeploy"). Bumped `sw.js`
|
||||||
|
`CACHE_NAME` v1→v2 to purge.
|
||||||
|
|
||||||
|
### C. Consent / DSGVO 500 "User not found" (FIXED, commit `52251cf`)
|
||||||
|
- `JwtAuthFilter` sets the Spring `Authentication` **principal to the userId (UUID)** — the JWT
|
||||||
|
subject is the userId, not the email. But `ConsentController.resolveUserId()` and
|
||||||
|
`DsgvoController.resolveUserId()` did `String email = auth.getName(); findByEmailAndTenantId(email, …)`.
|
||||||
|
Searching the email column for a UUID never matched → "User not found" → consent banner unusable
|
||||||
|
(check 404, Accept POST 500, button "didn't react"). Fixed by parsing `auth.getName()` as the userId.
|
||||||
|
|
||||||
|
### D. ⭐ THE BIG ONE — frontend never sends the access token (NOT yet fixed — your call)
|
||||||
|
This is the systemic bug and the reason curl/browser disagree:
|
||||||
|
|
||||||
|
- [`src/lib/api-client.ts`](../../cannamanage/cannamanage-frontend/src/lib/api-client.ts) accepts an
|
||||||
|
optional `token` param but **nothing ever passes it**. No service in `src/services/*` reads the
|
||||||
|
NextAuth session or attaches `Authorization: Bearer …`.
|
||||||
|
- So **every authenticated call from the browser reaches the backend with NO token.** Login works
|
||||||
|
only because `/api/v1/auth/*` is in the backend's `shouldNotFilter` allowlist.
|
||||||
|
- That's why `/consent/check`, `/dashboard/stats`, `/distributions/recent`, `/consent` etc. all
|
||||||
|
fail in the browser but **succeed when I curl them with a hand-added Bearer token.**
|
||||||
|
- The NextAuth JWT callback already stashes `token.accessToken` (see
|
||||||
|
[`src/lib/auth.ts`](../../cannamanage/cannamanage-frontend/src/lib/auth.ts)), but the `session`
|
||||||
|
callback does **not** expose it to the client, and `api-client` doesn't inject it.
|
||||||
|
|
||||||
|
**Two viable fixes (decide architecture):**
|
||||||
|
1. **Server-side proxy injection (recommended, most secure):** replace the static `next.config.mjs`
|
||||||
|
rewrite with a Route Handler at `app/api/backend/[...path]/route.ts` that reads the session via
|
||||||
|
`auth()` and forwards `Authorization: Bearer <token.accessToken>` to `BACKEND_URL`. Token never
|
||||||
|
touches client JS. Single choke point.
|
||||||
|
2. **Client-side token attach:** expose `accessToken` in the `session` callback, then have each
|
||||||
|
service (or a wrapped `apiClient`) call `getSession()` and pass `token`. Simpler but leaks the
|
||||||
|
access token into the browser and touches every service.
|
||||||
|
|
||||||
|
### E. Dashboard API contract mismatches (follow-up, non-fatal)
|
||||||
|
- Frontend calls `/dashboard/stats` + `/distributions/recent`; backend has no such routes
|
||||||
|
(`/clubs/me/stats` exists; `/distributions/recent` has no `/recent` mapping → 500). Dashboard
|
||||||
|
falls back to mock data so it renders. Either add the endpoints or fix the service paths + the
|
||||||
|
`ClubStats` DTO shape (frontend `totalStockGrams/distributionsToday/monthlyQuotaUsagePercent`
|
||||||
|
≠ backend `totalDistributionsThisMonth/totalGramsDistributedThisMonth/activeBatches`).
|
||||||
|

## 4. What we need in automated Playwright E2E tests
|
||||||
|
|
||||||
|
Goal: a CI-runnable suite that drives a **real browser** against the **real Docker stack** and
|
||||||
|
fails on exactly the classes of bugs above. The existing `e2e/mock-backend.mjs` mocks auth for
|
||||||
|
visual tours — that is NOT enough; it can't catch the token gap (D) or the principal bug (C)
|
||||||
|
because there's no real backend/JWT. We need a **real-stack** E2E profile.
|
||||||
|
|
||||||
|
### 4.1 Test harness
|
||||||
|
- Add `@playwright/test` with a `playwright.config.ts`:
|
||||||
|
- `webServer` / global-setup that runs `docker compose up -d --build` and waits for
|
||||||
|
`http://localhost:3000` + backend health, then seeds `init.sql`.
|
||||||
|
- `baseURL: http://localhost:3000`.
|
||||||
|
- Capture `trace`, `screenshot`, and **console + network** on failure.
|
||||||
|
|
||||||
|
### 4.2 Real-token auth fixture (the key piece you asked about)
|
||||||
|
We must obtain and use **real JWTs**, two complementary ways:
|
||||||
|
|
||||||
|
**(a) UI login fixture** — a Playwright `storageState` created once by logging in through the
|
||||||
|
real form, so the NextAuth session cookie is reused across tests:
|
||||||
|
```ts
|
||||||
|
// global-setup.ts
|
||||||
|
const page = await browser.newPage()
|
||||||
|
await page.goto('/login')
|
||||||
|
await page.fill('#email', 'admin@test.de')
|
||||||
|
await page.fill('#password', 'test123')
|
||||||
|
await page.click('button[type=submit]')
|
||||||
|
await page.waitForURL('**/dashboard')
|
||||||
|
await page.context().storageState({ path: 'e2e/.auth/admin.json' })
|
||||||
|
```
|
||||||
|
Then tests use `test.use({ storageState: 'e2e/.auth/admin.json' })`.
|
||||||
|
|
||||||
|
**(b) API token helper** — for direct backend assertions and for seeding state fast, fetch a real
|
||||||
|
JWT from the backend and reuse it:
|
||||||
|
```ts
|
||||||
|
export async function getApiToken(request, email='admin@test.de', password='test123') {
|
||||||
|
const res = await request.post(`${BACKEND_URL}/api/v1/auth/login`, { data: { email, password } })
|
||||||
|
return (await res.json()).accessToken // flat LoginResponse: {accessToken,refreshToken,expiresIn,role}
|
||||||
|
}
|
||||||
|
// use it: request.get('/api/v1/consent/check', { headers: { Authorization: `Bearer ${token}` } })
|
||||||
|
```
|
||||||
|
Store these in a `tokens` fixture so specs can hit the backend directly **and** the proxied
|
||||||
|
`/api/backend/*` path. Comparing the two is exactly how we'd have caught bug D automatically.
|
||||||
|
|
||||||
|
### 4.3 Specs to write (each asserts NO console/page errors + the right network result)
|
||||||
|
1. **Hydration smoke (catches A):** for every top route (`/login`, `/dashboard`, `/members`,
|
||||||
|
`/stock`, `/distributions`, `/reports`, `/portal-login`, `/pricing`, `/impressum`) — navigate,
|
||||||
|
assert `page.on('pageerror')` count == 0 and no `[console.error]`.
|
||||||
|
2. **PWA assets (catches B):** `GET /manifest.json` → 200 `application/json`; `GET /sw.js` → 200
|
||||||
|
`application/javascript`; assert NOT redirected to `/login`.
|
||||||
|
3. **Authenticated proxy carries the token (catches D — the big one):** after UI login, intercept
|
||||||
|
the request to `/api/backend/consent/check` and assert it (i) has an `Authorization` header by
|
||||||
|
the time it hits the backend and (ii) returns **200**, not 401/500. This is the test that would
|
||||||
|
have caught the whole token gap.
|
||||||
|
4. **Consent lifecycle (catches C):** fresh user → banner visible → click Accept → banner
|
||||||
|
disappears → `GET /api/backend/consent/check` returns `hasDataProcessingConsent: true` → reload,
|
||||||
|
banner stays gone.
|
||||||
|
5. **Dashboard data (catches E):** assert `/dashboard/stats` + `/distributions/recent` return 200
|
||||||
|
(once endpoints are aligned) and the dashboard shows real numbers, not mock fallback. Until
|
||||||
|
fixed, mark as `test.fixme` referencing the contract mismatch.
|
||||||
|
6. **Contract guard:** a spec that logs in via API helper and hits each documented backend route
|
||||||
|
with the real token, asserting 2xx — a cheap regression net for principal/route bugs.
|
||||||
|
|
||||||
|
### 4.4 CI wiring
|
||||||
|
- Run on the Docker stack in CI (compose service), `playwright test`, upload trace + screenshots
|
||||||
|
as artifacts. Gate merges on the hydration smoke + token + consent specs.
|
||||||
|
|
||||||

## 5. Status / handover
|
||||||
|
|
||||||
|
- Commits on `main`: `4be9c4c` (hydration + PWA), `26a77b5` (docs), `52251cf` (consent/dsgvo principal).
|
||||||
|
- Backend + frontend rebuilt and redeployed on TrueNAS; consent verified **at API level** (200/200/200).
|
||||||
|
- **OPEN — needs your decision + implementation:** bug **D** (token never attached). Until that's
|
||||||
|
fixed, the browser consent/stats calls still fail even though the backend is correct. Pick proxy
|
||||||
|
injection vs client attach (I recommend the server-side proxy Route Handler).

||||||
