Could not initiate Jitsi conference room

I am initializing the iframe but it is not starting the conference as it was doing before. It should start the conference as soon the iframe is initialized. I am getting the following error on the console.

(index):1705 Uncaught TypeError: Cannot set properties of undefined (setting 'sourceNameSignaling')

My code is below with the screenshot:

this.options = {
      width: 900,
      height: 700,
      configOverwrite: { prejoinPageEnabled: false },
      interfaceConfigOverwrite: {
        // overwrite interface properties
      parentNode: document.querySelector('#jitsi-iframe'),
      userInfo: {
        displayName: this.Candidate.candidatesName
      localRecording: {
        disable: false,
        notifyAllParticipants: true
    this.api = new JitsiMeetExternalAPI(this.domain, this.options);

Check the config.js on your deployment
