Common Mistakes

  • Using a Slack channel name instead of the channel ID — support_channel_id must be the ID (e.g. C0123456789)
  • Forgetting to invite the Slack bot to the support channel — alerts will fail silently
  • OpenAI API key has no credits — classification will fail and fallbacks will be used
  • Testing with already-read emails — the Gmail trigger only picks up unread INBOX messages
  • Different Gmail credentials on different nodes — use the same OAuth credential everywhere
  • Gmail OAuth missing gmail.send scope — auto-replies will fail
  • Expecting Slack alerts for auto-replied emails — only emails requiring human review alert Slack
