Solana: Error creating program: TypeError: Expected Buffer

I understand what’s going on here. The error message suggests that there is a problem with the “Buffer” type in your code, and it looks like you are trying to pass a React component (“Page”) as a prop to another React component (Client).

Here is an article that explains what might be wrong and how to fix it:

Error: TypeError: Buffer expected

When you try to create a new “Program” using the “use client” hook, the error message “TypeError: Buffer expected” indicates that there is a problem with the data passed to this function. Specifically, it looks like you are trying to pass a React component (“Page”) as a prop to another React component (Client), but React doesn’t know how to handle such props.

What’s new

In your code, you have imported the “use client” hook from “@solana/wallet-adapter-react-ui”. This hook allows you to create a new “Program” using the “Client” object. However, if you pass a “page” component as a prop to another React component (client), it will try to render that component in a way that React can’t understand.

Troubleshooting

To resolve this error, you need to make sure that your React components are receiving data in a format that the Use Client hook can understand. In particular, you need to use the idl object from @solana/wallet-adapter-react-ui to retrieve the program ID and other metadata.

Here is an updated version of your code that resolves this issue:

“jsx”

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 ID with idl

useEffect(() => {

WalletMultiButton.createProgramClient({

programId: programId,

idl: idl, // use the idl object to pass data to the client to use

});

}, [programId]);

return ;

}

“

In this updated version of your code, we use theuseEffecthook to create a newProgramclient with theWalletMultiButtoncomponent and theidlobject. We then pass theprogramIdvariable as a prop to ourPage` component.

If you follow these steps, you should be able to fix your error and get your React components working with the “use client” hook from @solana/wallet-adapter-react-ui.
