Error on first user signup - JSON.parse: unexpected character at line 1 column 1 of the JSON data

I'm trying to deploy the docker project on a personal server running Fedora Server 39 and Docker. Using basically default settings in my .env, and updating only NEXT_PUBLIC_WEBAPP_URL, NEXTAUTH_SECRET, CALENDSO_ENCRYPTION_KEY and POSTGRES_PASSWORD, I am getting this error when inviting my first user:

Adding ALLOWED_HOSTNAMES does not make a difference.

I also posted this on the Docker channel in Discord but given the presence of crypto and developer scam/spam bots it's very clear that the Discord community is unmoderated, hence filing this as an issue.

Any news? Did someone find out what is happening here? I'm running into the same issue here.
