Hi Tommy

We want users to click Join the video call button. As soon as they click, we are getting below error

here is the code:

$(function () { var joiningStack = @Html.Raw(Json.Encode(ViewData["zjoiningStack"])); var custdimp = @Html.Raw(Json.Encode(ViewData["user"])); //console.log (custdimp); //console.log('checkSystemRequirements'); //console.log(JSON.stringify(ZoomMtg.checkSystemRequirements())); //const zoomMeeting = document.getElementById("zmmtg-root"); //const ZoomMtg = document.getElementById("zmmtg-root"); // it's option if you want to change the jssdk dependency link resources. ZoomMtg.setZoomJSLib('https://source.zoom.us/1.7.2/lib', '/av'); ZoomMtg.preLoadWasm(); ZoomMtg.prepareJssdk(); console.log(JSON.stringify(ZoomMtg.checkSystemRequirements())); var signature; getSignature(); } document.getElementById('join_meeting').addEventListener('click', function (e) { e.preventDefault(); if (!this.form.checkValidity()) { alert("Enter Name and Meeting Number"); return false; } ZoomMtg.init({ leaveUrl: joiningStack[2], isSupportAV: true, videoHeader: true, success: function () { ZoomMtg.join( { meetingNumber: joiningStack[1], userName: custdimp, signature: signature, apiKey: joiningStack[0], userEmail: 'email@gmail.com', passWord: '', success: function (res) { $('#nav-tool').hide(); console.log('join meeting success'); }, error: function (res) { console.log(res); } } ); }, error: function (res) { console.log(res); } }); }); }); We are pushing joiningstick data from server.

Hi Tommy

I removed pace,js from page & error has gone but we are not able to see video ( just blank screen)

Also got this warning. We are on broadband & network speed should not be a problem.

Hey @customerservice,

Glad to hear the error is gone.

Have you tried clicking the turn video on button? Is there another participant in the call?

That chrome warning should not be an issue.

Thanks,
Tommy
