Internal Server Error after Manual Setup.

Getting this after Discord Auth:

This is in the terminal:

Here is the .env file

Any idea how to resolve this.

Also, problem in the Docker method:

I cannot seem to reliably reproduce this bug. Hmm, I'll see what I can figure out. Thanks for submitting the issue!

Regarding the Docker issue, I can build just fine with the example Compose file.

Turns out it only happens if you're logging in from an URL that is different than your callback URL:

I.e. if you're attempting to log in via http://127.0.0.1:8000 but your callback URL uses http://localhost:8000, your login will fail.

Let me know if this fixes your issue.
