Worked on stabilizing the Slack provider integration for the openclaw/openclaw repository, focusing on backend development and event handling using Node.js and TypeScript. Addressed a critical crash during Slack provider initialization by removing invalid event registrations for message.channels and message.groups, which conflicted with Bolt v4.6+ requirements. Centralized message handling through the unified message event and leveraged the channel_type field to maintain compatibility with newer Bolt versions. This targeted fix improved the reliability of Slack-based workflows by reducing startup errors and runtime crashes, while maintaining clear traceability through commit-level documentation for efficient review and potential rollback if necessary.
