Can anyone help me out, I’ve been stuck on this for days. I tried implementing the ReactJS chat using this [https://codesandbox.io/s/github/AmityCo/Amity-Social-Cloud-Web-Sample-Apps/tree/main/messaging-app-with-CRA?file=/src/ascClient.js:0-636](https://codesandbox.io/s/github/AmityCo/Amity-Social-Cloud-Web-Sample-Apps/tree/main/messaging-app-with-CRA?file=/src/ascClient.js:0-636) on a NextJS app.  
Each time I load the page I keep getting

```auto
Server Error
ASCError: ASCWebSDK: Only one instance of the SDK Web Client can be created

This error happened while generating the page. Any console logs will be displayed in the terminal window.

```

I cant figure to why this is happening.

Hey @coventi,

If you are just starting out I’d recommend you use the `Typescript SDK` instead.  
`npm i @amityco/ts-sdk`

To achieve the same as above you could use this snippet:

```auto
import { Client } from '@amityco/ts-sdk'

(async () => {
  const sessionHandler: Amity.SessionHandler = {
    sessionWillRenewAccessToken(renewal: Amity.Renewal) {
      renewal.renew();
      /*
       * If using an auth token
       *
       * try {
       * renew.renewWithAuthToken(authToken)
       * } catch() {
       * sdk will try to renew again at a later time
       *
       * renew.unableToRetrieveAuthToken()
       * }
       */
    },
  };
  const client = Client.createClient(API_KEY, API_REGION)

  let isConnected = await Client.login({ userId: USER_ID }, sessionHandler)
})()

```
