Guide Common problems

The AI assistant is not answering

Troubleshooting

In this order, from the most frequent to the rarest.

  1. Credit and credentials — Settings → AI Usage for the usage, AI Credentials for the keys. Credit run out or key revoked: the assistant goes quiet without warning anybody.
  2. Is the flow active? An AI Assistant node in an unpublished flow never comes into play.
  3. Does the trigger include that channel? The Channel Types boxes have to cover the channel the message arrives from.
  4. Has an operator replied? Pause bot replies after owner reply stops the bot for the configured time. That is the intended behaviour.
  5. Loop protection has tripped — if the conversation has passed the limit of automatic messages inside the rolling window, the automation is blocked until the re-enabling condition.
  6. Session closed — the user has typed the Stop Keyword.
  7. A Condition with no fallback — the conversation is stuck on a branch that does not exist.
  8. RAG on without Pinecone — with RAG Enhancement switched on and Pinecone credentials missing, the calls fail.
