Ethereum: Troubleshooting “Error HH604: Troubleshooting ‘missing trie node’ issue when forking BSC mainnet using Hardhat”

As a developer working with Ethereum, you are likely familiar with the excitement of building custom blockchain applications. However, even with experience, issues can arise when attempting to fork and deploy new chains. In this article, we will delve into the specifics of a common error that occurs when trying to forgo Binance Smart Chain (BSC) using Hardhat: “Error HH604: Troubleshooting ‘missing trie node’ issue.”

The Issue

When attempting to fork BSC mainnet using Hardhat, you may encounter an error related to missing trie nodes. The hardhat command, which is part of the popular development environment for Ethereum development tools (Hardhat), attempts to establish a connection with a BSC mainnet node. However, if there are issues with the connectivity or trie node configuration, this error can occur.

The Error HH604

Error HH604 indicates that there was an issue related to missing trie nodes, which is crucial for establishing a secure and functional blockchain network. The exact details of this error can vary depending on the version of Hardhat, BSC mainnet, and the underlying Ethereum development tools used.

Troubleshooting Steps

To troubleshoot the “missing trie node” error using Hardhat, follow these steps:

• Check your network connection: Ensure that your internet connection is stable and working properly.

• Verify node configuration: Double-check that you have correctly configured the BSC mainnet node using npx hardhat node --fork.

• Check for node issues: Look for any errors or warnings related to node connectivity or trie node configuration in your Hardhat logs.

• Update Hardhat and dependencies

  

  : Ensure that you are running the latest version of Hardhat and all required dependencies.

• Verify trie node usage: Check if the useTrie option is set to true when creating a new wallet or network object.

Example Solution

Here’s an example of how you can troubleshoot and resolve the “missing trie node” error using Hardhat:

const { HardhatRuntimeEnvironment } = require('hardhat');


async function main() {

  const { networks, getChainId } = await ethers.getNetworks();


  // Verify network configuration

  console.log(Available networks: ${networks});


  // Check for node issues

  if (getChainId() !== 'bsc-1') {

    throw new Error('Missing trie node error detected');

  }


  // Update Hardhat and dependencies

  await hardhatUpdate();

}


async function hardhatUpdate() {

  const { ethers } = require('@nomicfoundation/hardhat-ethers');


  // Update Ethers.js version

  await ethers.updateEthersVersion('4.10.0', '1.21.14');


  // Update Hardhat runtime version

  await ethers.updateRuntimeVersion('mainnet', '1.9.3');

}


main().catch((error) => {

  console.error(error);

});

By following these troubleshooting steps and example solution, you should be able to resolve the “missing trie node” error when attempting to fork BSC mainnet using Hardhat.
