We have a use case  to transfer an assignment from Person A to B, so we developed a local action and configured view to capture the operator to transfer to. Post activity of the FA is as shown in the attachment.

After execution of the activity, I expect it to show Review harness but it is showing some error on the screen. Transfer activity has no error and the assignment got transfer successfully. Its just the UI that shows error and confuses the user. Up on reload of browser, it shows Review harness.

Any ideas on how to approach these kind of issues? 

Below is the console log in chrome Developer tools:
