**Description**  
Hi,  
I have previously integrated Zoom Web SDK and I noticed that it stopped working due to not being able to load wasm files. Previously I was using 1.7.6 version so I updated it to use 1.9.1 but calling `ZoomMtg.setZoomJSLib('Zoom URL', '/av');` still cannot load required files.  
All requests made return 403 AccessDenied. I checked my signature and JWT tokens and they all look good.

I am loading Web SDK this way:

require(’@zoomus/websdk’);

ZoomMtg.setZoomJSLib(‘Zoom URL’, ‘/av’);  
ZoomMtg.preLoadWasm();  
ZoomMtg.prepareJssdk();

**Error**  
GET [https://source.zoom.us/1.9.1/lib/av/5510\_video.mt.wasm](https://source.zoom.us/1.9.1/lib/av/5510_video.mt.wasm) 403  
GET [https://source.zoom.us/1.9.1/lib/av/5510\_js\_media.min.js](https://source.zoom.us/1.9.1/lib/av/5510_js_media.min.js) net::ERR\_ABORTED 403

**Which Client Web SDK version?**  
Web SDK 1.9.1

Hey @daniels.pitkevics,

Thank you for reaching out to the Zoom Developer Forum. When testing with the latest version of the [Sample Web App](https://github.com/zoom/sample-app-web), I’m not seeing this same issue. I would first use that project as a repository to see if you can identify anythings that might be different.

Here are some things you can check as well:

1. Make sure that you’ve updated your local Zoom package to the latest version

2. If you’re using CDN resources, make sure those links are updated

3. Try using an import statement for the `ZoomMtg` object. Newer versions of Node.JS handle this differently than `require`.

In general, our guide on integrating the SDK should help here:

> **[Build an App - Web - Client SDKs - Zoom Software Development Kit (Zoom SDK)](https://marketplace.zoom.us/docs/sdk/native-sdks/web/build#integrate)**
>
> Build an App
> 
> This guide will walk through the steps to get started with the Web SDK through the following steps: 
> 
> Downloading the SDK
> 
> Integrating the...

If that doesn’t help, are you able to share a public git repo with the code that you’re using? I’ll work to reproduce the issue on my end.

Thanks,  
Max
