**I am working on next js 13 and using zoom sdk for my app requirements . I am getting this error when a user of my app is trying to join the meeting. Let me show you my code.**

**Code :**

```auto

const page = ({ params }: { params: IParams }) => {

    const { meetingId } = params;

    useEffect(() => {

        const initializeMeeting = async () => {
            try {
                const ZoomEmbed = (await import('@zoomus/websdk/embedded')).default;
                client = ZoomMtgEmbedded.createClient();

Hi @ravi.gupta ,

is it possible that the quotes for password are invalid?

```auto
password: `804939`
```

</div>

you can checked your signature on [https://jwt.io/](https://jwt.io/)

result payload

```auto
{
  "sdkKey": "JGZDvfh6Sey7Yjm7wimW9g",
  "mn": 89143717796,
  "role": 1,
  "iat": -1686291698,
  "exp": -1686291638
}

```

**iat** and **exp** of your signature is negative and **tokenExp** is missing

</div>

@ravi.gupta , your IAT and EXP are in negative value. you need them to be after EPOCH time

and yes @j.schoenemeyer mentioned your tokenExp is missing too

@chunsiong.zoom I’ve made it negative for generate a expired token. but after after adding tokenExp, the error is still the same

Hey @chunsiong.zoom can we connect somewhere can you please review my code? It is really very urgent that’s why I’m asking you.

you use React 18 ?

meeting SDK uses **React v16.13.0** and is - as far as I know - not compatible to React 17/18

</div>

@ravi.gupta ,

could you refer to this, and check if the existing JWT works with this code sample?

For client view, you will need to use react 16

</div>

in your screenshot there is a React 18 warning message “ReactDOM.render is no longer supported in React 18 …”

if you are running React 18, the meeting SDK cannot run anymore

React 16 is not compatible with React 17 or React 18
