When the Telegram OIDC widget fails to load (ad blockers, DNS, CSP),
the deep link polling fallback caused an infinite page reload:
1. pollDeepLinkToken received 202 (pending) which axios treated as success
2. loginWithDeepLink stored undefined tokens with isAuthenticated=true
3. checkAdminStatus() fired with invalid token → 401
4. Response interceptor called safeRedirectToLogin() → page reload → loop
Fixes:
- pollDeepLinkToken: validateStatus rejects non-200 (202 now caught in poll loop)
- AUTH_ENDPOINTS: add /cabinet/auth/deeplink/ and /cabinet/auth/login/auto
- safeRedirectToLogin: guard against redirect when already on /login
- loginWithDeepLink: validate response tokens before storing
- setTokens: validate tokens in store method (protects AutoLogin, VerifyEmail, etc.)
- Fix stale initData comparison in clearStaleSessionIfNeeded that destroyed
valid refresh tokens on mobile WebView reopens
- Restrict X-Telegram-Init-Data header to auth endpoints only
- Close Mini App on auth retry to force fresh initData from Telegram
- Merge Connection page error/not-configured states for better UX
- Remove unnecessary comments across 40+ files (section dividers,
restating comments, noise catch block comments)
- Configure ESLint allowEmptyCatch to properly handle intentional
empty catch blocks (62 warnings resolved)
The old clearStaleSessionIfNeeded stored initData in sessionStorage for
comparison, but sessionStorage is cleared on tab close — so switching
Telegram accounts between separate Mini App openings was never detected.
Fix: store the Telegram user ID in localStorage (survives tab close).
On every launch, compare the fresh initData user ID with the stored one.
If they differ, clear all auth tokens and cached user data to force
re-authentication as the correct account.
Telegram Mini App creates a new WebView on each open, clearing
sessionStorage. Combined with 24h auth_date validation on backend,
returning users couldn't re-authenticate after closing the app.
- Move refresh token to localStorage for persistence across sessions
- Keep access token in sessionStorage (short-lived, OK to lose)
- Fix auth store initialize() to recover when access token is missing
but refresh token exists in localStorage
- Remove separate mountThemeParams() call to fix ConcurrentCallError
(mountMiniApp() handles it internally in SDK v3)
- Update token migration logic for new storage strategy
- Skip token refresh/Bearer header for auth endpoints in request interceptor
- Wait for auth store initialization before attempting Telegram login
- Clear stale session tokens when init data changes (WebView persistence)
- Show backend error details instead of generic messages
