@ twilio / conversations JS SDK客户端未处理的拒绝，令牌已过期

如何解决@ twilio / conversations JS SDK客户端未处理的拒绝，令牌已过期

有人可以指出如何正确处理@twilio/conversations Client.create错误而不必使用处理unhandledrejection事件：

import { Client as ConversationsClient } from "@twilio/conversations";
// ...
    try {
      this.conversationsClient = await ConversationsClient.create('expired token');
    } catch (err) {
      // err: Unable to connect: Access Token expired or expiration date invalid
      console.error(err);
      return;
    }
// but later results in an unhandled rejection

我已经找到了代码：

// simplified stack trace (reversed):
ConversationsClient.create()
// browser/client.js: 
    new Client()
    _this.sessionPromise = _this.services.session.initialize();
    this.services.syncClient.list()
twilio-sync/lib/client.js:
    this._createList()
    this.services.network.post(this.services.config.listsUri,requestBody).then(response => response.body);
    // POST to https://cds.us1.twilio.com/v3/Lists

// which is implemented as:
    return this.executeWithRetry(() => this.transport.post(uri,headers,body),retryWhenThrottled);

    executeWithRetry(request,retryWhenThrottled = true) {
        return new Promise((resolve,reject) => {
            let codesToRetryOn = [502,503,504];
            if (retryWhenThrottled) {
                codesToRetryOn.push(429);
            }
            let retrier = new operation_retrier_1.Retrier(this.backoffConfig());
            retrier.on('attempt',() => {
                request()
                    .then(result => retrier.succeeded(result))
                    .catch(err => {
                    if (codesToRetryOn.includes(err.status)) {
                        let delayOverride = parseInt(err.headers ? err.headers['Retry-After'] : null);
                        retrier.failed(mapTransportError(err),isNaN(delayOverride) ? null : delayOverride * 1000);
                    }
                    else if (err.message === 'Twilsock disconnected') {
                        // Ugly hack. We must make a proper exceptions for twilsock
                        retrier.failed(mapTransportError(err));
                    }
                    else {
                        // Fatal error
                        retrier.removeAllListeners();
                        retrier.cancel();
                        reject(mapTransportError(err)); // THIS IS UNHANDLED
                    }
                });
            });

我当然不会故意这样做，但是经历了这一点后，我如何确定图书馆不会拒绝其他地方的承诺？

复制步骤：

1. 获取对话演示git clone [e-mail]:TwilioDevEd/conversations-demo.git
2. 将myToken设置为过期的
3. 打开localhost：3000并登录
