Loading Web SDK 1.9.1 returns 403 AccessDenied

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:


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

GET 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 net::ERR_ABORTED 403

Which Client Web SDK version?
Web SDK 1.9.1


Device (please complete the following information):

  • Device: Macbook Pro
  • OS: Mac OS 11.2.1
  • Browser: Chrome
  • Browser Version: 88.0.4324.192

Hey @daniels.pitkevics,

Thank you for reaching out to the Zoom Developer Forum. When testing with the latest version of the Sample Web App, 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:

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.
