Missing JsMediaSDK_Instance

Hi @tommy, I’m hosting locally but still I’m getting the error.

Uncaught SyntaxError: Unexpected token ‘<’ js_media.min.js:1


This snapshot is when I don’t start meeting. When I start meeting, then ReferenceError: JsMediaSDK_Instance is not defined error comes.

Additional Context
When I open downloaded webim.min.js and js_media.min.js in network panel, it opens my index.html page in response.

Finally, able to fix all issues and start meeting also. For the above issue, I fixed it by hosting from Source without a timeout.


ZoomMtg.setZoomJSLib(‘https://source.zoom.us/1.7.2/lib’, ‘/av’);

I hope, this answer helps whoever encounters this issue.

Hey @abhishekkr1993, glad you were able to fix the issue!

Thanks for posting your solution.


Well, that’s great, but I want to use my local copy!

Can the error that @abhishekkr1993 is experiencing with js_media.min.js be fixed? I’m also experiencing it.

Hey @ankhmor,

If you want to use local copy, please see the readme on the NPM package:

If you are using Angular by chance, here is how to include the local copy in your project:


I was facing the same issue, solve it by using 1.7.4 version , 1.7.2 is removed

ZoomMtg.setZoomJSLib(‘https://source.zoom.us/1.7.4/lib ’, ‘/av’);

Yep, upgrading to 1.7.4 is now required.
