Custom Action Does Not Return Data

Symptom: After running a test, the response area is empty or displays no usable data.

Reason: The endpoint may not be returning valid JSON, or the API does not include a response body. Adalo can only use structured JSON responses to create Outputs.

Solution: Check your endpoint in a tool like Postmanarrow-up-right to make sure it returns valid JSON. Confirm the response includes the data you expect and uses proper formatting with opening and closing brackets. If the request triggers a workflow in Make, ensure the scenario is configured to return data back to Adalo.
