Now Learning Lab Validator Stuck on "Validating Task" and Never Returns Result

[Rennie]

Hello,

I am experiencing an issue with a Now Learning ServiceNow lab.

I completed the task exactly as instructed:
- Created the incident with the required values.
- Set the caller to Adela Cervantsz.
- Assigned the incident to the Software group.
- Added the required customer-visible comment.
- Confirmed that the comment appears in the Activity stream.
- Saved the incident using Update.

When I click Validate Task, the status changes to "Validating Task..." but it never completes. It does not return either a pass or fail result, even after waiting several minutes.

Additional details:
- The issue occurred before and after the lab hibernated.
- I reopened the lab using Resume.
- The incident and comment are still present in the instance.
- I refreshed the lab page and retried validation multiple times.
- The validator remains stuck indefinitely.

I cannot continue with the course because I am blocked on this task.

Could someone please check whether there is an issue with the task validator or advise on how to proceed?

Thank you.

Hi @Rennie 

Are you impersonating the platform user to validate this? If yes, could you please add a screenshot as well?

Hello,

Thank you for your response .

The main problem is in my instance while troubleshooting the lab, I discovered that the user record "Adela Cervantsz" appears to have been deleted. The Caller field now shows "Invalid reference" when I try to use that user, and opening the record from History returns "Record not found." 

Could someone advise whether the lab instance can be reset or replaced so I can continue the exercise? 

Thank you.
