Troubleshooting

Fix Slack not_in_channel and channel_not_found in Duaer

When the Slack node in Duaer fails with not_in_channel, your Slack app is not a member of that channel. Invite the app to the channel.

Why Duaer shows these errors

  • not_in_channel: the channel exists, but your Slack app (bot) is not a member and cannot post.
  • channel_not_found: usually a private channel the app is not in, so it cannot see it; or the channel ID is wrong.

Fix it in Duaer

  1. In Slack, open the channel and send /invite @YourApp, or select Add apps under Integrations in channel details.
  2. Back in Duaer, pick the channel again from the list in the Slack node and select Execute step.
  3. To post to public channels without inviting each time, add the chat:write.public scope under OAuth & Permissions, reinstall the app, and reconnect the Slack credential in Duaer. Private channels still need an invite.

Questions

Can Duaer post to a private Slack channel?

Yes, after you invite your Slack app to that private channel so Duaer can see it.

Why does Duaer still fail after I added a Slack scope?

New Slack scopes apply only after you reinstall the app; then reconnect the Slack credential in Duaer.
