[Bug]: [CocosCreator] Argument of type 'Room<MyRoomState>' is not assignable to parameter of type 'Room<Schema>'. Type 'MyRoomState' is missing the following properties from type 'Schema': [$getByIndex], [$deleteByIndex]ts(2345)

Context

This is my code.

import { _decorator, Component, Node } from "cc";
const { ccclass, property } = _decorator;

import Colyseus from "db://colyseus-sdk/colyseus.js";
import type { MyRoomState } from "../../../../ColyseusServer/src/rooms/schema/MyRoomState";

@ccclass("Home")
export class Home extends Component {
    protected async start(): Promise<void> {
        const client = new Colyseus.Client("ws://localhost:2567");
        const room = await client.joinOrCreate<MyRoomState>("my_room");

        const $ = Colyseus.getStateCallbacks(room);
    }
}

This is the detailed error message.

Argument of type 'Room<MyRoomState>' is not assignable to parameter of type 'Room<Schema>'.
  Type 'MyRoomState' is missing the following properties from type 'Schema': [$getByIndex], [$deleteByIndex]ts(2345)

using the Colyseus Multiplayer SDK from the Cocos Store, I found error messages in colyseus.d.ts, and it seems like the corresponding npm packages couldn’t be found, etc.

I have also looked at this in detail, but unfortunately it did not solve the problem.
