A Slack fail condition occurs when we don't respond with HTTP 200 within 3 seconds after Slack calls our endpoint. If this happens, Slack will retry sending the same payload. This is often triggered because we need to perform callbacks when converting messages. To avoid sending the same message multiple times, we block subsequent retry calls from Slack. This commit returns early HTTP 200 response as soon as we get any retry calls from Slack. Part of #30465.
