使用NodeJS进行Sinch呼叫

Question

我正在尝试使用Sinch调用API进行基本的电话呼叫；但是，我总是遇到错误。到目前为止，我的代码只是简单地创建了SinchClient对象，然后尝试进行出站电话呼叫：

const express = require('express');
const app = express();
const SinchClient = require('sinch-rtc');

const sinch = new SinchClient({
    applicationKey: '********',
    capabilities: { calling: true }
});

app.post('/sinch', (req, res) => {
    console.log(req);
});

app.get('/', (req, res) => {
    console.log('testing');
    const callListeners = {
        onCallEstablished: (call) => {
            res.send(call.incomingStreamURL);
        }
    }
    const callClient = sinch.getCallClient();
    const call = callClient.callPhoneNumber('+46000000000');

    call.addEventListener(callListeners);
})

app.listen(8080, () => console.log('listening on port 8080'));

不幸的是，当我尝试运行我的应用程序时，我遇到了以下错误：

***-MacBook-Pro:** ***$ node index

这显然是node模块的当前版本中的Sinch SDK的问题；我似乎不能理解是什么导致了这个indexOf错误。我试图查看精简后的代码，发现问题出在userAgent.indexOf代码块上，但从那里看并没有多大意义。

如果我取出新的SinchClient代码块，错误就不再出现(我还注释掉了与Sinch代码有关的所有内容)。其他人也有类似的问题吗？知道为什么Sinch的nodejs模块似乎迎合了需要在浏览器上运行的代码吗？

Sinch库是一个客户端库，适用于带有webrtc和麦克风的浏览器，不能在节点服务器端使用。
