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 ` 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). +- Full per-bug detail is in [`cannamanage/docs/ROO-HANDOVER.md`](../../cannamanage/docs/ROO-HANDOVER.md) + and BigMind chunks 54/55/56 + facts 206/207/208. + +— Homelab Lumen
