Timeout or Large Payload Error

Symptom: The Custom Action fails to run or returns an error related to loading or timing out.

Reason: Custom Actions have a 30-second timeout and a 5MB response size limit. Large or complex responses may exceed these limits and cause the app to freeze or data not to load or update as expected.

Solution: Reduce the size of the response data or request only the fields you need. You can test the endpoint outside Adalo to confirm it returns quickly. For larger data sets, you may need to reconsider your workflow and use an external tool to set up as expected.
