Can't start WebSocket transport

I tested it in a separate bare project and it starts up fine.

const PORT = 7777
const HOST = "127.0.0.1"
var _server = WebSocketMultiplayerPeer.new()

func _ready():
    var err = _server.create_server(PORT, HOST)
    if err != OK:
        print("Unable to start server")
        set_process(false)
    else:
        print("Server started")

const PORT = 7777
const HOST = "127.0.0.1"
var _server = WebSocketMultiplayerPeer.new()

func _ready():
    var err = _server.create_server(PORT, HOST)
    if err != OK:
        print("Unable to start server")
        set_process(false)
    else:
        print("Server started")

I also tried changing the port and that didn't do anything.

Oh okay. I found the problem. create_server is being called twice and it errors out on the second call. What's the best way to go about editing the auto-generated files from rivet_sdk?

we have our plugin source code at https://github.com/rivet-gg/plugin-godot, if you'd like to tinker with that and build from source

I assume it's being generated by the rust plugin, with most of the code being from the toolchain repo?

yeah it looks like rivet-plugin-godot (https://github.com/rivet-gg/plugin-godot/tree/main/rust/rivet-plugin-godot) provides bindings between the toolchain and godot

i think the code youre looking for is in this file https://github.com/rivet-gg/plugin-godot/blob/main/examples/lobbies_servers/addons/rivet_sdk/multiplayer_manager.gd, which says its autogenerated but i think thats just because it gets copied into the plugin thats likely the file to edit
