When a logged in user does not have the permission to read the process instance, then in Tasklist fetching the process instance to retrieve the business key fails with a status code 404. As a result, a failure that the business key could not be retrieved is shown.

AT:

• whenever the request to retrieve the business key fails, the failure is dropped and the business key input field is not shown
• the exception is not visible

Hint:

• even when the logged in user does not have the permission to read the process instance the status code 404 is returned.
