Initial Docker setup error: SyntaxError: JSON.parse unexpected end of data (lemmy.ca)

I have been struggling with getting a docker setup of lemmy running on amr64 server and I almost got it going.

docker compose up -d

Then i go to my domain.com/setup and try to make my first admin user.
When I click Sign Up, I get an error:

SyntaxError: JSON.parse: unexpected end of data at line 1 column 1 of the JSON data

Server:

VPS, 2 cpu cores, 12 GB ram Ubuntu OS Caddy as reverse proxy, but I left nginx in the docker-compose file

I am running this on an arm64 server and there isn't an official docker build for arm.

I figured out how to get past that screen.

I added this to my Caddyfile after reading this https://caddy.community/t/caddy-v2-how-to-proxy-websoket-v2ray-websocket-tls/7040/9

tw.arkadi.one {
        import caddy-common
        reverse_proxy   http://localhost:1234

        @websockets {
                header Connection Upgrade
                header Upgrade websocket
        }

        handle @lemmy {
                reverse_proxy @websockets   http://lemmy_lemmy_1:8536
}

I got my instance running. Thanks for the suggestions.

Lemmy 0.18.x doesn't use websockets that I know, so I'm not sure why this helped.

I mentioned you are trying to use arm on GitHub... https://github.com/LemmyNet/lemmy/issues/3102

Thanks! I was going to post something on the documentation github about my hack. I'm not sure why it worked but adding that worked.

Maybe it is something to do with Caddy and Nginx not working well together?

We really need an ARM build of this though.
