Here's the hardhat.config.js, as per the reference: hardhat mainnet forking
module.exports = {
solidity: '0.8.9',
networks: {
hardhat: {
// Ref: https://hardhat.org/hardhat-network/guides/mainnet-forking.html
forking: {
url: 'https://public-node.rsk.co/',
blockNumber: 4e6,
},
},
},
};
When running npx hardhat test, the following error/ stacktrace is output:
Main
1) "before all" hook in "Main"
0 passing (4s)
1 failing
1) Main
"before all" hook in "Main":
