* fix(telegram): handle Grammy HttpError network failures (#3815)
Grammy wraps fetch errors in an .error property (not .cause). Added .error
traversal to collectErrorCandidates in network-errors.ts.
Registered scoped unhandled rejection handler in monitorTelegramProvider
to catch network errors that escape the polling loop (e.g., from setMyCommands
during bot setup). Handler is unregistered when the provider stops.
* fix(telegram): address review feedback for Grammy HttpError handling
- Gate .error traversal on HttpError name to avoid widening search graph
- Use runtime logger instead of console.warn for consistency
- Add isGrammyHttpError check to scope unhandled rejection handler
- Consolidate isNetworkRelatedError into isRecoverableTelegramNetworkError
- Add 'timeout' to recoverable message snippets for full coverage
- Add bot.catch() to prevent unhandled rejections from middleware
- Add isRecoverableNetworkError() to retry on transient failures
- Add maxRetryTime and exponential backoff to grammY runner
- Global unhandled rejection handler now logs recoverable errors
instead of crashing (fetch failures, timeouts, connection resets)
Fixes crash loop when Telegram API is temporarily unreachable.
The Telegram webhook and monitor now accept and pass through accountId and config parameters, enabling routing and configuration per Telegram account. Tests have been updated to verify correct bot instantiation and DM routing based on accountId bindings.
Previously, grammY's default bot.start() processed updates sequentially,
blocking all Telegram messages while one was being handled. This made
maxConcurrent settings ineffective for Telegram.
Now uses @grammyjs/runner which processes updates concurrently, matching
the behavior of Discord (Promise.all) and WhatsApp (fire-and-forget).
Benefits:
- Ack reactions (👀) appear immediately, not after queue clears
- Multiple chats can be processed in parallel
- maxConcurrent setting now works correctly for Telegram
- Long-running tool calls no longer block other conversations
