Webfinger giving Internal Server Error and exception error in logs

[HighWingy]

Describe the bug Going to the url for webfinger on my Nextcloud gives an internal server error. And when I check the logs, I see the following message:

Exception parse_str(): Argument #1 ($string) must be of type string, null given in file '/opt/nextcloud/apps/social/lib/WellKnown/WebfingerHandler.php' line 235

To Reproduce Steps to reproduce the behavior:

1. Go to https://cloud.home.dragongames.net/index.php/.well-known/webfinger
2. See error

Expected behavior I'm not entirely sure what is supposed to happen as I've never been able to get this to work. But I do know that the 500 error and the error in the log file are not correct

Screenshots n/a my site is public ish
