The Audit Suggestion warning is issued in the following situations:
'Log Error' should be set to 'Yes' for 'AllExceptions" error handler at screen flow level: you have an Error Handler, in a screen flow, to catch general exceptions and the Log Error property is set to No.
You should change the Log Error property to Yes because, since the Error Handler is catching all exceptions, it is advisable that detailed information about that exception is logged by OutSystems Platform. This might allow you to discover the reason for the exception. Learn more about Logs of exceptions.
Clicking the symbol will take you directly to the Error Handler element in your flow.
