I understand what is happening here. The error message suggests that there is a problem with the Buffer' type in your code, and it looks like you're asking to pass a React component (Page) as a property to another React component (the client).

When you ask to create a newProgramusing theuse clienthook, the error message "TypeError: Expected Buffer" suggests that there is a problem with the data passed to this function. In particular, it looks like you're asking to pass a React component (Page) as a property to another React component (the client), but React doesn't understand how to handle such properties.

In your code, you imported theuse clienthook from@solana/wallet-adapter-react-ui. This hook allows you to create a newProgramusing aclientobject. However, when you pass aPagecomponent as a property to another React component (Client), it tries to render that component in some way that React can't understand.

To fix this error, you need to make sure that your React components receive data in a format that theuse clienthook can understand. In particular, you need to use theidlobject from@solana/wallet-adapter-react-uito get the program ID and other metadata.

import { useEffect } from 'react';
import WalletMultiButton from '@solana/wallet-adapter-react-ui';
import idl from '@/app/idl/idl.json';
const Page = () => {
// display your page component here
};
export default function App() {
const programId = 'your-program-id'; // get the program identifier using idl
useEffect(() => {
WalletMultiButton.createProgramClient({
programId: programId,
idl: idl, // use the idl object to pass data for use by the client
});
}, [programId]);
return ;
}

In this updated version of your code, we use the useEffecthook to create a newProgramclient using theWalletMultiButtoncomponent and anidlobject. We then pass theprogramIdvariable as a property to ourPagecomponent.

By following these steps, you will be able to correct your error and make your React components work with theuse clienthook from@solana/wallet-adapter-react-ui`.
