JS error while testing web client

I am getting this error while testing the sample project given in github. I changed api key and secret as it is advised in the documentation. Can anyone explain why I am getting this error and how to avoid it? Thanks

Find the line that says: (It is line 45) 
<script src="https://source.zoom.us/zoom-meeting-1.2.4-min.js"></script>

Replace it with: 
<script src="https://source.zoom.us/zoom-meeting-1.2.4.min.js"></script>

I am getting the same problem. The Zoom Meeting js is returning a 403, unauthorized. 

Hi Michael, 

Please use the below line. 

Replace it with: 
<script src="https://source.zoom.us/zoom-meeting-1.2.4.min.js"></script>

Let me know if that works for you.
