Harness Fail when launch harness from a case button

Hi, I have a requirement where I need system to take user to a different harness when he Cancel current working case. I tried adding an action set to the cancel button to launch harness but getting HarnessFail error. I’ve attached the pega log. Please help.

Solution: instead of opening the case by handle, I changed to open assignment by pzInskey. The section cancel button stayed the same and issue is resolved.

Cause: I’m not sure why that solved the problem. I posted a discussion maybe people know the answer will share details Difference between open work by handle VS open assignment | Support Center (pega.com)

@ChensuZ5 this appears to be a duplicate of your other question Difference between open work by handle VS open assignment.
