Hi and thank you for your amazing work, really! Excalidraw is beautiful, but at the same time when it's coming to self-host it's a mess and your work is incredibly valuable in that sense.

After reading up all across the issues, I came to a partially working state. Everything is accessible online behind a Caddy reverse proxy on TLS certificated, the collaborative part is fully functional and reactive, but the storage does not work. Everything else is (I mean vector drawings works unitl reload or image upload).

Any clue on this error?

Seems weird that GET, will not be recognized noop?

Here my Caddyfile

whiteboard.example.com {
    reverse_proxy 192.168.3.202:8880
}

whiteboard.example.com/api/v2 {
    reverse_proxy 192.168.3.202:8881
}

whiteboard.example.com/socket.io/ {
    reverse_proxy 192.168.3.202:8882
}

And here the compose.yaml
