Hi, I have a question if this web SDK is supported to use with [asp.net](http://asp.net)?  
I can connect to the meeting but all feature is not working. The image below is the error for what I try on no 1,2,and 3.  
For no 1 & 2 I can connect to zoom then try to chat.  
For no 3 I can’t connect at all

 ![error1](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/2X/d/d21c01b1a708855205519e7682d1d7708120887e.png)

What I try:

1. using iframe I can connect but all feature not working

> `<div class="iframe-container" style="overflow: hidden; padding-top: 56.25%; position: relative;"> <iframe allow="microphone; camera" style="border: 0; height: 100%; left: 0; position: absolute; top: 0; width: 100%;" src="" frameborder="0" sandbox="allow-forms allow-scripts allow-same-origin allow-pointer-lock allow-popups"></iframe> </div>`

1. I move all the code from the CDN sample app and again I got the very same error with the first one

2. I try to follow the steps in zoom marketplace  
Code this script to replace index.js (I don’t want external js, i’m still testing this thing).

> `ZoomMtg.preLoadWasm();  
> ZoomMtg.prepareJssdk();

```
    const meetConfig = {
        apiKey: '',
        meetingNumber: '',
        leaveUrl: 'mylocaltestsite',
        userName: 'abcd',
        userEmail: '', // required for webinar
        passWord: '', // if required
        role: 0 // 1 for host; 0 for attendee or webinar
    };

    ZoomMtg.init({
        leaveUrl: meetConfig.leaveUrl,
        isSupportAV: true,
        success: function () {
            ZoomMtg.join({
                signature: document.getElementById('<%= LblToken.ClientID %>').innerText, //this is generated signature in code behind (copy from the site signature example code for c#)
                meetingNumber: meetConfig.meetingNumber,
                userName: meetConfig.userName,
                apiKey: meetConfig.apiKey,
                userEmail: meetConfig.userEmail,
                passWord: meetConfig.password,
                success: (success) => {
                    console.log(success)
                },
                error: (error) => {
                    console.log(error)
                }
            })
        }
    })`

```

All error seems happened in zoom javascript. What do I do wrong and what can I do?

Thanks

Hey @irvanwijayaludianto,

> [@irvanwijayaludianto](#):

> ` meetingNumber: NUMBER,`

Please try passing in the meeting number as a number and not a string.

Let me know if that fixes the issue.

Thanks,  
Tommy
