Sixth E2E bug, surfaced after the page.goto-domcontentloaded fix
finally let the navigation complete. The harness now reaches the
canvas-root selector wait but still times out because the canvas
never renders:
TimeoutError: page.waitForSelector: Timeout 45000ms exceeded.
waiting for [aria-label="Molecule AI workspace canvas"]
Root cause: canvas/src/components/AuthGate.tsx wraps the page,
fetches /cp/auth/me on mount, and redirects to the login page when
the response is 401. The bearer header we set via
context.setExtraHTTPHeaders works for platform API calls but does
NOT satisfy /cp/auth/me — that endpoint is cookie-based (WorkOS
session). So:
1. AuthGate mounts
2. Calls fetchSession() → /cp/auth/me → 401 (no session cookie)
3. AuthGate transitions to anonymous → redirectToLogin()
4. Browser navigates away from tenant URL
5. The React Flow canvas root with the aria-label never mounts
6. waitForSelector times out at 45s
Fix: context.route() intercepts /cp/auth/me and returns a fake
Session JSON so AuthGate resolves to "authenticated" and renders
its children. The session contents are cosmetic — Session.org_id
and Session.user_id appear in a few canvas surfaces but never fail
on dummy values.
This is the cleanest fix path. Alternatives considered + rejected:
- Add a ?e2e=1 backdoor to AuthGate: production code shouldn't
have a "skip auth" flag, even gated.
- Real WorkOS login flow in Playwright: too much overhead per run.
- Skip the canvas UI test, test only API: defeats the point of
the staging E2E (which is to catch UI regressions before
promotion).
After this lands the harness should reach the workspace-node click
step and exercise tabs — only then can a real product bug (rather
than a test-harness bug) surface. The 6-bug chain mapped to:
1. instance_status field name (#2066)
2. staging.moleculesai.app DNS zone (#2066)
3. X-Molecule-Org-Id TenantGuard header (#2066)
4. Hydration selector waited pre-click (#2066)
5. networkidle never settles (this commit's parent)
6. AuthGate /cp/auth/me redirect (this commit)
