"punycode.ucs2.decode undefined" when ever _resumeConnection() is called.

Description

lib-jitsi-meet/modules/xmpp/ResumeTask.js

Line 126 in ed2a0e6

const url = new URL(this._stropheConn.service);

The app crashes whenever the internet connection is interrupted because of URL class of javascript.

Possible Solution

We were able to fix it by bypassing the code.

Steps to reproduce

• Step-1 Use the bundled lib-jitsi-meet
• Step-2 Bundle your javascript code
• Step-3 Use the bundled code in your react-native
• Step-4 When on call just turn off the wifi the app will crash.

Environment details

React-Native (all latest versions)

What BOSH URL are you using?

[kaushikRitik]

this is the option we are passing in the makeConnection
{ hosts: { domain: domain, muc: "conference." + domain, focus: "focus." + domain, }, serviceUrl: "wss://xmpp." + domain + "/xmpp-websocket", bosh: "https://xmpp." + domain + "/http-bind", }

What is your domain?

[kaushikRitik]

domain is "test.ritik.io"

Since you are using LJM directly, are you polyfilling URL? We use https://github.com/charpeni/react-native-url-polyfill without problems.

[kaushikRitik]

We are also using the polyfills like used in jitsi meet but we still got the error.

Here is the fix if anyone else got this error.

 _resumeConnection() {
    const { streamManagement } = this._stropheConn;
    const resumeToken = streamManagement.getResumeToken();

    // Things may have changed since when the task was scheduled
    if (!resumeToken) {
        return;
    }

    logger.info('Trying to resume the XMPP connection');
    let url = this._stropheConn.service;
    let search = url.includes("?") ? url.replace(/.*\?/, "?") : "";
    const pattern = /(previd=)([\w-]+)/;
    const oldToken = search.match(pattern);

    // Replace previd if the previd value has changed.
    if (oldToken && oldToken.indexOf(resumeToken) === -1) {
        search = search.replace(pattern, `$1${resumeToken}`);

    // Append previd if it doesn't exist.
    } else if (!oldToken) {
        search += search.indexOf('?') === -1 ? `?previd=${resumeToken}` : `&previd=${resumeToken}`;
    }
    url = url.includes("?") ? url.replace(/\?.*/, search) : url + search;
    this._stropheConn.service = url.toString();

    streamManagement.resume();
}
