Lindy(3)
- My apologies [Name], I'm having trouble completing this task.The agent gave up on the task because it didn't know how to finish it, lacked the right tool, or didn't understand the instructions.
- Task Stopped Due to Insufficient CreditsYour account ran out of monthly credits, so Lindy paused your agents and put new tasks on hold until you have credits again.
- The Input provided is too longYour agent tried to process more text/context than the underlying AI model can handle in one step, so it stopped instead of finishing.
n8n(3)
- A Chat Model sub-node must be connected and enabledDraftYour AI Agent has no 'brain' attached. An AI Agent node can't run on its own — it needs a language model (like an OpenAI or Anthropic chat model) plugged into it, and that model node has to be turned on.
- The requested webhook "[METHOD] [path]" is not registered. Click the 'Execute workflow' button on the canvas, then try again. (404 not found)Draftn8n received a call to your webhook URL but isn't currently listening on that address, so it returned a 404 (not found). Usually it means you used the test URL without first pressing the run button, or you used the test URL when you should be using the live one.
- The resource you are requesting could not be found (404)DraftThe outside service your node is calling said 'I don't have anything at that address.' Something about the URL, the ID, or the request method is wrong, so the service can't find what you asked for.
