Facing Issues with Parsing JSON information using Custom Connector

(1) ShareShare
ReportReport
Posted on by DY-12051428-0 2
Action 'Get_Records' failed: Http request failed: the content was not a valid JSON. Error while parsing JSON: 'Unexpected character encountered while parsing value: E. Path '', line 0, position 0.'
 
I am trying to fetch information from my Custom connector, which takes in content type as application/json. It is being triggered by a manual triigger, which does provide the output in the form of application/json, yet I am getting the error above.
 
I have looked at the raw output of the trigger, and it looks like a JSON format.
 
How do I resolve this?

    The error indicates your custom connector is returning a non-JSON response, likely starting with an unexpected character like 'E' — often seen with HTML error pages (e.g., Error 403, Error 500, etc.).
    1. Check Raw Response from the custom connector (not just the trigger input).
    2. Verify the API endpoint is:
      • Returning proper application/json response.
      • Not returning an HTML error or plain text (e.g., "Error occurred").
    3. Add error handling (e.g., Configure Run After) to inspect failed responses.
    4. Use Postman or curl to test the connector endpoint independently and confirm it returns valid JSON.
