Zoom Web SDK whiteboard file upload

Whiteboard in Zoom Web SDK throws the following CORS error on file upload

Access to fetch at ‘https://nws.zoom.us/nws/das/api/v1/documents/XX/upload?name=360_F_159183621_0YTKAAqAA7GI7DlCBfYJ2wfK…’ from origin ‘http://localhost:3001’ has been blocked by CORS policy: Response to preflight request doesn’t pass access control check: No ‘Access-Control-Allow-Origin’ header is present on the requested resource. If an opaque response serves your needs, set the request’s mode to ‘no-cors’ to fetch the resource with CORS disabled.

Could you provide the precise steps to replicate the issue you’re encountering? Additionally, have you attempted to use the Chrome Origin Trial or any of the other solutions outlined in the help documentation linked here:


Yes, I enabled the shared array buffer, although I have the gallery view enabled it is still not working.

I am using the JWT Authentication
