After entering the username in the login dialog, we're getting "Internal Server Error" messages. A little bit more digging shows a failed API call to `/api/signin-flow` endpoint, returning a HTTP 500 with a response that looks like so:
```
{"statusCode":500,"error":"Internal Server Error","message":"Cannot read properties of undefined (reading 'replace')"}
```
The result is that no one is able to log into the instance.
What's wrong here and how do we fix it?
Posting on behalf of a friend Ophestra (npub16sg…xv0y) to help her log back into the instance~
