My Angular Code  
startMeeting() {  
let signaturedata = ZoomMtg.generateSignature({

```
  meetingNumber: this.meetConfig.meetingNumber,
  apiKey: this.meetConfig.apiKey,
  apiSecret: this.meetConfig.apiSecret,
  role: this.meetConfig.role,
  success: (res) => {
    console.log(res.result);
  }
});

document.getElementById('zmmtg-root').style.display = 'block'

ZoomMtg.init({
  leaveUrl: '',
  isSupportAV: true,
  success: (success) => {
    console.log(success)

    ZoomMtg.join({
      signature: signaturedata,
      meetingNumber: this.meetConfig.meetingNumber,
      userName: this.meetConfig.userName,
      apiKey: this.meetConfig.apiKey,
      userEmail: '',
      passWord: this.meetConfig.passWord,
      success: (success) => {
        console.log(success)
      },
      error: (error) => {
        console.log(error)
      }
    })

  },
  error: (error) => {
    console.log(error)
  }
})

```

Hey @dev8,

Pease share your [Web SDK signature](https://marketplace.zoom.us/docs/sdk/native-sdks/web/essential/signature) to [developersupport@zoom.us](mailto:developersupport@zoom.us) so I can debug.

Thanks,  
Tommy
