ws websocket不会将数据发送到服务器

Question

打开后，我需要websocket发送请求。目前，websocket已成功打开，但之后将不会发送该请求。

const WebSocket = require("ws");
const request = require("request");
const querystring = require("querystring");
const dotenv = require('dotenv');
const fs = require("fs");
const uuid = require("uuid");
dotenv.config();


function initialize() {

    var options = {
        method: "POST",
        url: process.env.URL,
        headers: { "content-type": "application/x-www-form-urlencoded" },
        body: querystring.stringify({
            grant_type: "password",
            username: process.env.USERNAME,
            password: process.env.PASSWORD,
            client_id: process.env.CLIENT_ID,
            client_secret: process.env.CLIENT_SECRET
        })
    };

    return new Promise((resolve, reject) => {
        request.post(options, (error, response, body) => {
            if (error) {
                reject(error);
            } else {
                resolve(JSON.parse(body));
            }
        })
    })
}

var tokenInit = initialize();

tokenInit.then((result) => {
    console.log("Getting Access_Token!");
    process.env.ACCESS_TOKEN = result.access_token;
    process.env.REFRESH_TOKEN = result.refresh_token;
    console.log("Finished!");
    console.log(`Your Access Token is: ${process.env.ACCESS_TOKEN}`);
})
.then(() => {
    connect().then(server => {
        id = "002dad7c-0359-4c86-aa66-48952712a452";
        server.send(`{\"channel\": \"device.helix\", \"subscribe\": {\"deviceId\": \"${id}\"}}`, () => {
            console.log("request sent");
        });
    })
    .catch(err => {
        console.log(err);
    });
})
.catch((err) => {
    console.log("Something went wrong");
    console.log(err);
})


function connect() {
    return new Promise(function (resolve, reject) {
        var server = new WebSocket(`${process.env.WSS}${process.env.ACCESS_TOKEN}`);
        server.onopen = function () {
            resolve(server);

            server.on("message", function incoming(data) {
                d = JSON.parse(data);
                console.log(data);
            });

        };
        server.onerror = function (err) {
            reject(err);
        };

    });
}

我希望获得发送请求的代码，该请求应返回成功消息。目前，我仅收到一条消息，说明已建立连接
