Infinite loop when trying to login

## Describe the bug

Hello,
I host Owncloud OCIS app in TrueNas Scale.
Recently, maybe after some upgrade of the app, I cannot login to Owncloud anymore.
I get into an infinite loop when I try to login.

The earliest error is `runtime error: invalid memory address or nil pointer dereference`..

Here is the log:
```
