BUG: auth_test() not wrapped in try-except in fi_slack.py causing bot crash on invalid token

[flexus-teams]

Error Summary

The auth_test() call in fi_slack.py at line 708 is not wrapped in a try-except block, causing the bot to crash when encountering an invalid, expired, or revoked Slack token.

Stacktrace

The SlackApiError exception propagates up from the auth_test() call and crashes the bot when authentication fails.

Investigation Findings

Root Cause

File: flexus_client_kit/integrations/fi_slack.py
Line: 708
Function: join_channels()

Why: The auth_test() call on line 708 is not wrapped in a try-except block. When the Slack API returns an invalid_auth error (due to invalid/expired/revoked token), the SlackApiError exception propagates up and crashes the bot. This is inconsistent with the error handling pattern used for other Slack API calls in the same method (users_list, conversations_list), which are all wrapped in try-except blocks.

Code Snippet

async def join_channels(self):
    if not self.reactive_slack:
        return
    web_api_client: AsyncWebClient = self.reactive_slack.client
    my_info = await web_api_client.auth_test()  # <-- NO TRY-EXCEPT HERE
    my_user_id = my_info["user_id"]
    logger.info(f"Bot user ID: {my_user_id}")

    try:  # <-- Other API calls ARE wrapped
        users_response = await web_api_client.users_list(limit=5000)
        ...
    except SlackApiError as e:
        logger.exception("Failed to list users")
        self.problems_other.append(...)

Fix Suggestion

Wrap the auth_test() call (lines 708-710) in a try-except block to gracefully handle authentication failures. The bot should log the error to self.problems_other and continue or exit gracefully, similar to how other Slack API errors are handled. This will prevent the bot from crashing when the Slack token is invalid, expired, or revoked.

Secondary Issue

The configuration for this specific karen bot instance has an invalid/expired/revoked SLACK_BOT_TOKEN. While the code should handle this gracefully, the token itself needs to be regenerated or reconfigured in the bot's setup.
