Error running app with default port

[EatonEmmerich]

I am running a custom domain.
I have updated my compose file to remove Caddy as I couldn't get it working and duplicated the configuration on Traefik instead.

After some configuration changes I got the app running and routed correctly, but I am getting the following error opening the login page:

Screenshot of application error:

UPDATE: the cors policy is a red herring as it simply relates to reporting the actual error.
Running the revolt/client server on a different port using docker compose exec -it web sh and manually executing yarn run start:inject seems to give me a working login page.
UPDATE UPDATE: the working page only works if the server is no longer connected so it was a red herring in a red herring.
Currently still investigating.

Update:
Got some more error output for what was attempting to be reported (but blocked by revolt) to reporting.revolt.chat:

TypeError: Cannot read properties of undefined (reading 'invite_only')
