ServiceNow Learning 55: Flow error handler in ServiceNow

[Shamma Negi]

Hi All,

Today I am showing some light on how to handle flow errors in ServiceNow.

Enable flows to catch errors. Run a sequence of actions and sub flows to identify and correct issues. For example, have flows log output values, send notifications, and run corrective sub flows when they produce an error.

What are its Benefits:

Enable a flow error handler to gain these benefits.

• Automate the identification of flow errors as they happen. Capture and push flow error information rather than manually search for issues caused by flow errors.
• Automate the resolution of flow errors. Run actions and subflows to update records rather than manually updating records affected by flow errors.
• Build your own action error handling logic. Specify when actions return an error rather than always return an error.

What are Error Handler components

Error Handler user interface components

Flow error handling consists of these components:

1. Error Handler switch Option to enable or disable flow error handling. When enabled, the flow displays the Error Handler section. 2. Error Handler section Section of flow that runs when the flow catches an error. Use this section to automate the identification and resolution of flow errors. You can add up to 10 items in this section.

Note: The 10-item limit includes any combination of actions, flow logic, or subflows.

3. Error Status Object data pill containing details about the error caught by the flow. 4. Error Status > Code Integer data pill indicating whether the flow produced an error. By default, a value of 1 indicates that the flow produced an error. A value of 0 indicates that the flow ran successfully. You can define your own error codes when you create a custom action. 5. Error Status > Message String data pill containing the error message produced by the action, step, or system operation.Hope this helps.
