Hey @camillo ,

Can you please share what you are passing in for `ZoomMtg.init()` and `ZoomMtg.join()`? That is most likely where the issue is.

(Please don’t include any sensetive info like the meeting number, signature, and api key).

Thanks,  
Tommy

Thanks @tommy, here are the details:

```
ZoomMtg.init({
        leaveUrl: window.location.href,
        // isSupportAV: true,
        success: () => {
          ZoomMtg.join({
            meetingNumber: this.meetConfig.meetingNumber,
            userName: this.meetConfig.userName,
            signature: this.signature,
            apiKey: this.meetConfig.apiKey,
            userEmail: "email@gmail.com",
            passWord: this.meetConfig.passWord,
            success: function (res) {
              console.log("join meeting success");
            },
            error: function (res) {
              console.log("error on console", res);
            },
          });
        },
        error: function (res) {
          console.log(res);
        },
      });
```

Are you getting these success or error logs? Or is `ZoomMtg.join()` not firing?

Can you share a screenshot of this white empty screen?

Thanks,  
Tommy

Exactly @tommy … `ZoomMtg.join()` is not firing, I do not get any _success_ nor _error_

The blank white screen is … just white, meeting number available from backend, but not able to join.

Thanks @camillo .

This can happen if an unexpected value is passed into the SDK `ZoomMtg.join()` function. It fails silently.

Can you please email the exact values you are passing in to [developersupport@zoom.us](mailto:developersupport@zoom.us) (include a link to this thread) and I will take a look. 🙂

Thanks,  
Tommy

Thanks @tommy …put me on the right direction. Issued solved; overall, it was the element id `zmmtg-root` that I was handling in a certain way in Web Sdk 1.9.0 with a transparency; apparently, that was creating some conflict in 1.9.9.  
Once I could “see” the Join, the only other fix was the meetingNumber as `int`.

Thanks for your help.

@ [camillo](https://devforum.zoom.us/u/camillo),  
Can you please pass the code or steps how to set value of _SharedArrayBuffer_ to _true_ using WebIsolation.

I have stuck in the same kind of issue.  
That will helpful.

</div>

@vbhosale  
I am using it through a Laravel backend, to overcome _SharedArrayBuffer_, I had to implement a _custom-made_ middleware where I set the appropriate _cors_ as required:

```auto
...
  ->header('Cross-Origin-Embedder-Policy', 'require-corp')
  ->header('Cross-Origin-Opener-Policy', 'same-origin')
...

```
