Error handling

It is possible that a REST API request may result in an error.

• You must always check for error or _error in the response and if the value is Y, then you can conclude that the API has resulted in an error.

• You must check for errorTitle and errorMessage for the reason for the failure. If the failure is due to the expired sessionId passed, then sessionExpired will be set to Y.

• For debugging, you can check the corresponding sqlCall for the SQL query that caused the exception, and the corresponding datasource call for the datasource that caused the exception.

• If the client user is an administrator, then an additional attribute adminMsg is populated with a more detailed error message.
