Why do I get the error ‘Unused Respond to Webhook node found in the workflow’ when calling my localhost webhook URL from a JavaScript script, but the same workflow works fine without errors when using a tunnel URL?
The error occurs because the “Webhook” node isn’t configured correctly. You need to set the “Response mode” option to “Using ‘Respond to Webhook’ Node” in the Webhook node settings. This ensures the workflow sends the response through that node and prevents the “Unused Respond to Webhook node found in the workflow” error.
