Unable to use Assistants - (WARNING:tornado.access:404)

I seem to be unable to use the assistants. When I click the reload button nothing happens in the frontend and in the docker logs it shows this:

lsp-1                     | WARNING:tornado.access:404 GET /pyright (172.19.0.5) 1.48ms

lsp-1                     | WARNING:tornado.access:404 GET /diagnostic (172.19.0.5) 0.45ms

I am using caddy, but through https://github.com/lucaslorentz/caddy-docker-proxy. The labels are:

windmill_server:
    ...
    labels:
      caddy: "windmill.example.org"
      caddy.tls.dns: "cloudflare <snip>"
      caddy.tls.resolvers: 1.1.1.1
      caddy.handle_path: /*
      caddy.handle_path.0_reverse_proxy: "{{upstreams 8000}}"

lsp:
    ...
    labels:
      caddy: "windmill.example.org"
      caddy.tls.dns: "cloudflare <snip>"
      caddy.tls.resolvers: 1.1.1.1
      caddy.handle_path: /ws/*
      caddy.handle_path.0_reverse_proxy: "{{upstreams 3001}}"

windmill_server:
    ...
    labels:
      caddy: "windmill.example.org"
      caddy.tls.dns: "cloudflare <snip>"
      caddy.tls.resolvers: 1.1.1.1
      caddy.handle_path: /*
      caddy.handle_path.0_reverse_proxy: "{{upstreams 8000}}"

lsp:
    ...
    labels:
      caddy: "windmill.example.org"
      caddy.tls.dns: "cloudflare <snip>"
      caddy.tls.resolvers: 1.1.1.1
      caddy.handle_path: /ws/*
      caddy.handle_path.0_reverse_proxy: "{{upstreams 3001}}"

which result in the Caddyfile:

windmill.example.org {
    handle_path /* {
        reverse_proxy 172.19.0.13:8000
    }
    handle_path /ws/* {
        reverse_proxy 172.19.0.12:3001
    }
    tls {
        dns cloudflare <snip>
        resolvers 1.1.1.1
    }
}

windmill.example.org {
    handle_path /* {
        reverse_proxy 172.19.0.13:8000
    }
    handle_path /ws/* {
        reverse_proxy 172.19.0.12:3001
    }
    tls {
        dns cloudflare <snip>
        resolvers 1.1.1.1
    }
}

So to my knowledge this should work fine. What am I missing?

I unfortunately do not know but would advise trying a simpler setup first to isolate if it's truly coming from your config

I'd guess that the LSP expects /ws/* and your Caddyfile config is re-writing the paths as / (i.e, without the /ws prefix that comes from the proxy server).

~~Ah, seems like you are right, that seems to be the case. Will have to read up on how to fix that😅~~ The way I did test that was opening a local windmill with the default values. Production (https://windmill.example.org/ws/) returns OK -> this does not work Testing (http://localhost/ws/) returns 404: Not Found ~~-> this works~~ Maybe instead of returning OK consider to return a page "Hey, it seems you've configured this wrong"? Oh no, wait a second, that can't be. If that was the case, I would not get the logs above as the requests would not reach the lsp container. I very much overthunk it. The working labels are:

windmill_server:

      caddy.@ws.1_header: Upgrade websocket
      caddy.0_reverse_proxy: "@ws {{upstreams 3001}}"
      caddy.1_reverse_proxy: /ws/*
