Some Slack events are delayed or missing

Incident Report for PullFlow

Postmortem

Slack events were getting reverified by API after being processed by queue. The queue was not sending verification header to API which was causing the verification exception in “isProduction” mode.

The queue endpoint change was only tested locally and the ‘isProduction’ path was not executed.

Lesson: Always test on preflight since it emulates isProduction
