inMeetingServiceListener throwing an error

[bmalik (Bhawana)]

I am using Zoom web sdk version 2.7.1.

The code is:-

$.ajax({
type: “GET”,
url: appGetSecureURL(‘/api/web/fetchzoomzaktoken/’),
success: function(a){
debugger;
console.log(a);
var data=$.parseJSON(a)
var zaktoken=data.zaktoken;
const client = ZoomMtgEmbedded.createClient();
let meetingSDKElement = document.getElementById(‘root’);
//client.init({ zoomAppRoot: meetingSDKElement, language: ‘en-US’ });

                client.init({
                    zoomAppRoot: meetingSDKElement,
                    language: 'en-US',
                    customize: {
                      video: {
                        isResizable: true,
                        viewSizes: {
                          default: {
                            width: 1500,
                            height: 800
                          }                             
                       
                                            
                        }
                      }
                    }
                  })
                

                client.join({
                    sdkKey: 'sdkkey',
                    signature: jwttoken,
                    meetingNumber: '88539350532',
                    password: '697236',
                    userName: 'Dpsdoctor',
                    zak:zaktoken
                    
                })

                
                $("#root").removeAttr("style");

                client.inMeetingServiceListener('onUserJoin', function (data) {
                    debugger;
                    console.log(data);
                  });

                  client.inMeetingServiceListener('onMeetingStatus', function (data) {
                    debugger;
                    // {status: 1(connecting), 2(connected), 3(disconnected), 4(reconnecting)}
                    console.log(data);
                  });
                
                //console.log(jwttoken);
                
               
            }
        });

I am able to start the meeting as a host . But the issue is that in the console I can see an error :- client.inMeetingServiceListener is not a function

Though If I execute client.getAttendeesList({}) , I can see the attendees list . Let me know how to resolve this issue.
