N8n live-chat on website being triggered and returning empty result

Questions
1

I have the n8n chat running as my trigger node live on a website. A few times, I have had the workflow triggered, but with the output being an empty JSON. Has anyone seen this before and know why it happened? (I can’t send a message to the AI, without typing something in the live chat)

It sounds like your “When chat message received” node might be triggering without receiving actual chat input, causing an empty JSON output. Here are a few steps to troubleshoot:

- Ensure the chat input field is correctly configured and visible on your website.

- Double-check the webhook URL and ensure it’s correctly linked to your workflow.

- Test the workflow manually by sending a message through the chat to verify if the issue persists.

For more detailed guidance, refer to the [n8n documentation](https://docs.n8n.io). If the problem continues, consider checking similar issues on [GitHub](GitHub · Where software is built).
