Workflow error handling

The personalized JavaScript that users create in workflow activity variables is vulnerable to run-time syntax errors. Available error information is available in a tooltip when you point to a workflow activity in an error state.

In the base system, workflow activities do not provide condition routing on the error state. As a result, the workflow progresses based on the state of the current record. For example, a workflow contains an Approval - User activity that uses an advanced script to add additional approvers. A syntax error in the script results in no approvers being added. Because a state of no approvers is a valid return, even without the syntax error, the approval activity is skipped and the workflow progresses along a positive path. However, this might not be a valid response for the workflow designer who does not want the workflow to progress along the positive path without approvers.

Workflow error handling detects and logs syntax errors and provides a state that the workflow designer can use to add error conditions to the workflow. Use error handling to locate syntax errors in advanced script fields for these workflow activities:

• Approval - User
• Approval - Group
• Catalog Task
• Create Task
• If
• Run Script
• Notification

• Workflow error tracking features
  Error handling provides visual cues within the workflow, such as error descriptions for activities in pop-ups, and detailed log records.
• Create an error condition exit
  An administrator can reroute the workflow when a script error occurs by creating an error condition exit for specific activities within the workflow. This allows the workflow to process script errors in a predictable way and not create undesirable results.
• Reconfigure an approval condition
  Approval activities react differently to script errors than the other activities.
