Error: Failed to decode result data on Metamask Hardhat Local Blockchain
The “error: failed to decode result data” message is typically returned by the MetaMask library when an error occurs while decoding data from the Ethereum blockchain. In this case, we are using Hardhat to connect to a local blockchain instance and have encountered an issue with the Metamask library.
1. Step 2: Check the MetaMask Library Documentation
Before diving into the code, be sure to check the official MetaMask library documentation to see what error message you are receiving. Specifically, check the [2. [error] documentation, which explains that this error can occur when using the “encrypt” function to decode data from the Ethereum blockchain.
2. Step 2: Check the Hardhat Configuration
Hardhat requires special configuration to work with a local blockchain instance. Make sure you have configured your Hardhat correctly:
const hardhat = request('hardhat');
module.exports = {
// ... other settings ...
network: {
provider: "
ethersProvider: {
host: '127.0.0.1',
port: 8545,
gas: 2000000, // or the value corresponding to the configuration
gasprice: 10000, // weiben
maxGasLimit: 15000000, // in bytes
},
},
};
3. Step 2: Verify the Ethereum blockchain data
Make sure you can retrieve data from the Ethereum blockchain without any problems. You can use the console.log' function or a library like
ethers.js’ to inspect the blockchain data:
const Web3 = request('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();
4. Step 2: Check the display function
Now let’s focus on the display()
function in the App.jsx file:
// display.js
import { display } from 'bsc-blocks';
export default function display() {
// Here is the display logic
}
// main.js (where display() should be used)
import React, { useState, useEffect } from 'react';
import display from './display';
function App() {
const [blockNumber, setBlockNumber] = useState(0);
useEffect(() => {
getBlockchainData();
return() => {
// Clear timers or events
};
}, []);
return (
Blockchain Number: {blockNumber}
);
}
export default application;
In this example, we add a “display” function that uses the “getBlockchainData()” function to retrieve and display data from the Ethereum blockchain.
5. Step 2: Test your code
Try running your code in a local development environment (such as Webpack Dev Server) or use a pre-built blockchain simulator such as Hardhat Local Blockchain. If you are still experiencing issues, please provide more details about your setup and code, including any error messages or relevant settings.
I hope this helps you troubleshoot the issue with Metamask on Hardhat Local Blockchain!
