Facing the same issue. Were you able to resolve it?
@michael.harrington Are you able to assist?

@tommy, @Michael_Purnell

try creating meetingConfig variable and pass to join()

var meetingConfig = {
meetingNumber: this.meetingNumber,
signature: this.signature,
apiKey: this.apiKey,
passWord: this.password,
success: function(res){
error: function(res) {

leaveUrl: this.returnUrl,
success: function () {
ZoomMtg.join( meetingConfig );
error: function(res) {

it is not giving me toString() error

I tried this solution, but the error persist…

I debugged this issue in Zoom library, the error is in file zoomus-websdk.umd.min.js and on line meetingNumber: e.meetingNumber.toString()
I tried with latest SDK 1.7.8 also.
It is not working on Local as well

Hey @nilesh.bunde,

Can you please share your init and join meeting code snippets along with steps to reproduce the issue so I can debug?


Hi @tommy,
The issue got resolved in v1.7.8

Hi Tommy and thanks for checking. I was, after upgrading to 1.7.8 I had a jquery issue (turned out I had two jquery references). It seems to be resolved now. Thank you.
