[react-native] Cannot read property 'addstream' of undefined

Hi! And thanks for this awesome package.

I’ve been trying for some weeks to integrate lib-jitsi-meet into our react-native app. It seems that I’m very close to getting it done but failing because of some detail that I can’t find.

I can establish connection successfully and enter a room, but no remote tracks are received. Upon entering, this error pops up:

Seems to be something with the RTCPeerConnection polyfill, already tried messing up with that with no luck. I’ve copied all polyfills under /features/mobile/polyfills from the jitsi-meet app. Is there anything else I should be looking for?

Using jitsi-meet app to connect to our backend works flawlessly.

react-native: 0.61.5
lib-jitsi-meet: commit de57cdfb6f2ac422901ade3cf0b4e130144c45ca from earlier this week
react-native-webrtc": 1.75.3

Config used (I think it shouldn’t matter because I used the same to test on jitsi-meet app):

  options = {
    hosts: {
      domain: 'xxx.yyy.com',
      muc: 'conference.xxx.yyy.com',
    bosh: 'https://xxx.yyy.com/http-bind',
    clientNode: 'http://jitsi.org/jitsimeet',
    testing: {
      p2pTestMode: false,
    enableNoAudioDetection: true,
    enableNoisyMicDetection: true,
    resolution: 720,
    constraints: {
      video: {
        height: {
          ideal: 720,
          max: 720,
          min: 240,
    channelLastN: -1,
    openBridgeChannel: true,
    enableWelcomePage: false,
    enableUserRolesBasedOnToken: false,
    p2p: {
      enabled: true,
      stunServers: [
        { urls: 'stun:meet-jit-si-turnrelay.jitsi.net:443' },
    makeJsonParserHappy: 'even if last key had a trailing comma',

Thanks in advance!

Just updated react-native-webrtc to 1.84.0 but the error persists

I’ve reproduced the same error on a clean repo (https://github.com/thiagobrez/react-native-jitsi-test).

Installed lib-jitsi-meet and its dependencies, and added a textinput and button to connect to a room, using jitsi beta servers.

Could anyone take a look?

Thanks in advance.

hello, @thiagobrez
did you found a solution>?

Yes @gorbatenkov ! Replace the file as suggested in React native + lib-jitsi-meet - audio/video tracks not getting added to the conference · Issue #1296 · jitsi/lib-jitsi-meet · GitHub
