Hey Guys,  
I’m trying to give video SDK a shot, however, when I try to join, I get the following two errors:

1. index.umd.js?a087:1 Uncaught ReferenceError: JsMediaSDK\_Instance is not defined
2. index.umd.js?a087:1 Uncaught TypeError: Cannot read properties of undefined (reading ‘userRole’)

And here is how I init:  
await client.init(“en-US”, “CDN”, {  
webEndpoint: “[zoom.us](http://zoom.us)”,  
stayAwake: true,  
});

```
    await client
      .join(
        `Test`,
        zoomSignature,
        id,
        password
      )

```

Any thoughts?  
I’m using Next JS.

Thanks do you have an estimate for when I will hear an update on that?

Hi @ha.hassanzadeh ,

How did you import the SDK into your file? If you a screenshot of the code snippet, that would be helpful, as well.

Thanks,

I tried two ways, both leading to the same result,

1. Regular import: import ZoomVideo from “@zoom1234/videosdk”;
2. Import inside sideEffect : const {default: ZoomVideo} = await import (" @zoom1234/videosdk")

Calling initialization and join is shown above.

@ha.hassanzadeh ,  
Got it. Have you also created your client (ZoomVideo.createClient() ) before calling .init?

Yes, without the client object how can I call client.init or client.join?
