Mayuri was playing with uploads while pulp was trying to convert us to a non-admin:

5:32PM ERR recovered panic in worker with error: runtime error: invalid memory address or nil pointer dereference error="runtime error: invalid memory address or nil pointer dereference" request_id=59c0e013-e3d6-4fda-aefb-1fca7c726e32 task_id=c6079ec3-71c2-4a9f-8e31-7b24d5bb42f7 task_type=add-uploads-repository

we might check the add-uploads-repository task to verify that all errors are handled, and possibly try locally to change the password to an invalid one and try calling this task to reproduce

If you can't reproduce or find the lack of nil checking in half a day, close and mark as NOTABUG
