What happens if an error occurs during the execution of a flow?

When an error occurs during the execution of a flow in ServiceNow's Flow Designer, the flow stops executing by default. This behavior is designed to prevent further actions from occurring that could be based on faulty data or conditions. Stopping the execution allows for the identification and resolution of the error without causing additional complications or errors downstream in the workflow.

In situations where you want to handle errors differently, such as logging them or attempting to recover from them, you can implement error handling mechanisms within the flow. However, if no error handling is specified, the default behavior is to halt the flow upon encountering an error. This ensures that any subsequent actions that depend on the successful completion of earlier steps do not execute under erroneous conditions, which could lead to invalid results or further errors.
