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

**Error**  
Uncaught SyntaxError: Unexpected token ‘\<’ js\_media.min.js:1

**Snapshot**

 ![Screenshot 2020-03-27 at 12.20.05 PM](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/2X/5/5334017aba549599812c5ec9ac9900167a52f415.png)

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.

**Code**

> ZoomMtg.setZoomJSLib(‘[https://source.zoom.us/1.7.2/lib](https://source.zoom.us/1.7.2/lib)’, ‘/av’);  
> ZoomMtg.preLoadWasm();  
> ZoomMtg.prepareJssdk();

I hope, this answer helps whoever encounters this issue.

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:

> **[@zoomus/websdk](https://www.npmjs.com/package/@zoomus/websdk)**
>
> Zoom Web SDK

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

Thanks,  
Tommy

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