Hey @avglive.developer,

In your `ZoomMtg.join` function, you have misspelled `userEmail` and the `passWord` property is also missing.

Please try fixing those and let me know if it works.

Thanks,  
Tommy

```

My idea is to get the minimal implementation of zoom working, and then start customizing and play.  
Thanks in advance.

Hey @avglive.developer,

Make sure you have the pre functions called after you import ZoomMtg:

```auto
import { ZoomMtg } from '@zoomus/websdk';
 
ZoomMtg.preLoadWasm();
ZoomMtg.prepareJssdk();

```

> **[@zoomus/websdk](https://www.npmjs.com/package/@zoomus/websdk#usage)**

Thanks,

Hi @tommy!  
I just updated the code but im getting the save behavior:

```
import React, { useEffect } from 'react';

import { ZoomMtg } from '@zoomus/websdk';

console.log('checkSystemRequirements');
console.log(JSON.stringify(ZoomMtg.checkSystemRequirements()));

ZoomMtg.preLoadWasm();
ZoomMtg.prepareJssdk();

const apiKeys = {

  error(res) {
    console.log('Joining meeting Error');
    console.dir(res);
  },
  success() {
    console.log('Success');
  }
};

export default () => {
  const joinMeeting = (signature) => {
    ZoomMtg.init({

        console.dir({ ...meetConfig, signature });
        ZoomMtg.join({ ...meetConfig, signature });
      }
    });
  };

  useEffect(() => {
    /**

Seems like some div id has to be referenced? But most of react projects im seeing hasn’t references to an id or something.  
This is the elements tree.

Hey @avglive.developer,

Try passing in the meetingId as a number and not a string.

If that does not work, send me your github repo with the issue so I can reproduce the issue locally.

Thanks,

Hey @avglive.developer,

Can you please try the following:

Add `https://` to the leaveUrl value:

> <https://github.com/avg-developer/av-live/blob/feature/zoom-first-approach/src/screens/ZoomTest/index.js#L37>

Try using a valid email, the special character might be breaking things:

> <https://github.com/avg-developer/av-live/blob/feature/zoom-first-approach/src/screens/ZoomTest/index.js#L21>

Let me know if that fixes the issue! 🙂

Thanks,

@tommy thanks for yout patience.

I just updated with a valid email and change the leave url with the same as the method definition here: [https://zoom.github.io/sample-app-web/ZoomMtg.html#init](https://zoom.github.io/sample-app-web/ZoomMtg.html#init)

Is not working, i’ve updated the branch if you want to check.

Hey @avglive.developer,

Are you still seeing the same error? Please reference our working sample app to see what is different with your app:

Hi @tommy, seems that the error is clearer now:

This is the console:

Is it related to [My API\_Key is not 22 characters, so why is the code checking this condition? It is 36 characters! - #6 by tanderson](https://devforum.zoom.us/t/my-api-key-is-not-22-characters-so-why-is-the-code-checking-this-condition-it-is-36-characters/19220/6?!)

If it is, is there a workaround?  
Thanks!

Hey @avglive.developer,

Double check you are using a [JWT App](https://marketplace.zoom.us/docs/guides/build/jwt-app) for the Web SDK and not an [SDK App](https://marketplace.zoom.us/docs/guides/build/sdk-app).

Thanks,  
Tommy

Hey @avglive.developer,

Strange, can you share the [Web SDK Signature](https://marketplace.zoom.us/docs/sdk/native-sdks/web/essential/signature) you are generating to [developersupport@zoom.us](mailto:developersupport@zoom.us) so I can debug?

Thanks,  
Tommy

```
 <link type="text/css" rel="stylesheet" href="https://source.zoom.us/1.7.2/css/bootstrap.css" />
    <link
      type="text/css"
      rel="stylesheet"
      href="https://source.zoom.us/1.7.2/css/react-select.css"

```

And its working like a charm.
