  Debugging: Use transaction codes like /IWFND/ERROR_LOG to check for any additional error messages or logs that can provide more context on the issue.
  Testing with Tools: Use tools like Postman or SAP Gateway Client (transaction /IWFND/GW_CLIENT) to test the OData service and inspect the raw response. This can help identify any discrepancies in the response format.
