I Need help with typescript classes

import Diagram from "../diagram/Diagram";
import MainEngine from "../MainEngine";
import { CommandData } from "../managers/CommandManager";
import User from "../core-models/UserModel";

export default abstract class Command<D>{
    function: Function;
    data: D;
    user: User;
    engine: MainEngine
    diagram: Diagram
    constructor(commandData:CommandData){
        this.function = async () => {};
        this.data = commandData.data;
        this.user = commandData.user;
        this.engine = commandData.session._engine;
        this.diagram = commandData.session._diagram;
    }

    public async execute(){
        await this.function();
    }

}

import Command from "./Command";
import { CommandData } from "../managers/CommandManager";
import ResponseCommand from "./ResponseCommand";

export default class CommandGetVncUrl extends Command<any>{

    constructor(commandData:CommandData, response:ResponseCommand){
        super(commandData);
        this.function = async () => {
            try {
                const device = this.diagram.selectDeviceById(this.data);
                if(device){
                    const url = await this.engine._cloudMngr.getConsoleUrl(device.getDeviceData(), this.user);
                    response.setData({url}).send();
                }
            } catch (error) {
                throw Error();
            }
        }
    }
