Describe the bug
When I try to delete user, the alert message popups and it says Expectation Failed

To Reproduce
Steps to reproduce the behavior:
0. Proxy Nginx Container itself to subdomain : nginx.example.com and access through the domain.

Go to 'Users' tab
Click on menu button with 3 dots at the right end of each rows.
Click "Delete 'USERNAME' "
When modal pops, Click "Yse, I'm Sure" button.

Similar error popup shows in deleting proxy rules, 404 rules, etc.
