How to Get the Name of the Failing Activity in a Workflow?

Issue Description:
In the context of a workflow or application, it is often crucial to identify the specific activity that has encountered an error or exception. This information is vital for debugging and troubleshooting purposes. When an activity within a workflow fails, it is required to retrieve its name programmatically to pinpoint the source of the issue.

Resolution:
To obtain the name of the failing activity, you can utilize the expression exception.source. This expression provides access to the name or identifier of the activity that triggered the exception. By using this approach, you can efficiently capture the failing activity's name for further analysis and diagnosis.

Here's a step-by-step guide on how to retrieve the name of the failing activity using the exception.source expression:

  1. Identify Exception Handling Scope: Ensure that your workflow or code includes an appropriate exception handling mechanism. This could involve using try...catch blocks, error handlers, or other similar constructs to capture exceptions when they occur.

  2. Capture the Exception: Within the exception handling scope, when an activity encounters an error, an exception object is generated. This object contains valuable information about the error, including the source of the exception.

  3. Retrieve the Failing Activity's Name: To access the name of the failing activity, use the exception.source expression. This expression retrieves the identifier of the activity that triggered the exception.
