We have a taks that raises following error if we try to access it in any way (edit, view, history, context menu in issues list view ). The issue although is correctly listed in issue list view, and all values get displayed. We are not sure, since when that raises, but the issue was moved between projects in history, that is what we can remember, although that don't have to be the cause for that error.

How can we accces that issue again, or at least remive it completly
