Troubleshooting

This section covers the most common issues encountered when using the Eledo node in n8n.

Authentication Errors​

If authentication fails:

  • Verify that the API Key is correctly entered in the n8n credentials.
  • Ensure there are no extra spaces when copying the key.
  • Try generating a new API key in your Eledo account and updating the credential.

Refer to the Authentication documentation for full setup instructions.

Empty or Unfilled PDF​

If the generated PDF contains only static template text and no dynamic data, check the following:

  • No fields were added in Guided Fields mode.
  • The JSON payload is empty ({}) or null.
  • Field names in JSON do not match the template exactly.

Review the Guided Fields and JSON Mode sections to confirm proper data mapping.

JSON Errors​

There are two types of JSON-related errors:

1. Invalid JSON Syntax​

If the JSON is malformed (missing brackets, commas, or quotation marks), n8n will return a validation error before sending the request.

Ensure your JSON:

  • Uses proper quotation marks
  • Has matching {} and []
  • Does not contain trailing commas

2. Template Validation Errors​

If the JSON syntax is valid but the structure does not match the template, Eledo may return an error message explaining the issue.

Review the template structure in the Eledo API section and verify that field names and nesting match exactly.

Node Not Visible in n8n​

If you cannot find the Eledo node in n8n:

  • Confirm that the node is installed.
  • Ensure you are the instance owner (required for installing verified community nodes).
  • Restart your n8n instance after installation if necessary.

Refer to the Installation section for detailed instructions.
