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 Postman 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.
