Fixes#27189
When an inbound message is debounced, the Bot Framework turn context is
revoked before the debouncer flushes and the reply is dispatched. Any
attempt to use the revoked context proxy throws a TypeError, causing the
reply to fail silently.
This commit fixes the issue by adding a fallback to proactive messaging
when the turn context is revoked:
- `isRevokedProxyError()`: New error utility to reliably detect when a
proxy has been revoked.
- `reply-dispatcher.ts`: `sendTypingIndicator` now catches revoked proxy
errors and falls back to sending the typing indicator via
`adapter.continueConversation`.
- `messenger.ts`: `sendMSTeamsMessages` now catches revoked proxy errors
when `replyStyle` is `thread` and falls back to proactive messaging.
This ensures that replies are delivered reliably even when the inbound
message was debounced, resolving the core issue where the bot appeared
to ignore messages.
Update tests to properly wait for async file upload operations:
- Use vi.waitFor() to wait for async upload completion in success case
- Use vi.waitFor() to wait for error message in cross-conversation case
- Add setTimeout delay for decline case to ensure async handler completes
- Adjust assertion order to match new execution flow (invokeResponse first)
The tests were failing because the file upload now happens asynchronously
after sending the invokeResponse, so we need to explicitly wait for the
async operations to complete before making assertions.
Fix file upload 'Something went wrong' error by sending the invoke
acknowledgement before performing the file upload, rather than after.
Changes:
- Move invokeResponse to fire immediately upon receiving fileConsent/invoke
- Handle file upload asynchronously without blocking the response
- Update test to wait for async upload completion using vi.waitFor
This prevents Teams from timing out while waiting for the HTTP 200
acknowledgement during slow file uploads to OneDrive.
