Error: Unable to decode result data in local Metamask Hardhat blockchain

The error: could not decode result data' message is usually returned from the MetaMask library when an error occurs when decoding Ethereum blockchain data. In this case, we use Hardhat to interact with a local instance of the blockchain, and we encounter a problem with the Metamask library.

Before diving into the code, make sure you check the official MetaMask library documentation for the specific error message you're encountering. In particular, check the [Error 2] section of the documentation, which explains that this error can occur when using theencodefunction to decode Ethereum blockchain data.

const hardhat = require('hardhat');
module.exports = {
// ... other configurations ...
network: {
provider: '
ethersProvider: {
host: '127.0.0.1',
port: 8545,
gas: 2000000, // or an appropriate value for your setup
gasPrice: 10000, // in wei
maxGasLimit: 15000000, // in bytes
},
},
};

Make sure you can get Ethereum blockchain data without any problems. You can use the console.logfunction or a library likeethers.jsto check the blockchain data:

const Web3 = require('web3');
const web3 = new Web3();
// Get blockchain data from MetaMask
async function getBlockchainData() {
try {
const result = await web3.eth.blockNumber();
console.log(result);
return result;
} catch (error) {
console.error(error); // Output: "Error: Failed to decode result data (value='0x', info={)"
}
}
getBlockchainData();

Now let's focus on your display()function in your App.jsx file:

// display.js
import { display } from 'bsc-blocks';
export default function display() {
// Your display logic is here
}
// main.js (where you will use display())
import React, { useState, useEffect } from 'react';
import display from './display';
function App() {
const [blockNumber, setBlockNumber] = useState(0);
useEffect(() => {
getBlockchainData();
return () => {
// Clear any timers or events
};
}, []);
return (

Blockchain number: {blockNumber}
Display blockchain data
);
}
export default App;

In this example, we added a displayfunction that uses thegetBlockchainData()` function to retrieve and display the Ethereum blockchain data.

Step 5: Test Your Code

Try running your code in a local development environment (such as Webpack Dev Server) or using a ready-made blockchain simulator such as Hardhat Local Blockchain. If you’re still having trouble, please provide more details about your setup and code, including any relevant error or configuration messages.

Hope this helps you fix the Metamask problem on your local Hardhat blockchain!
