Unable to setup hardhat free gas network

[gabrielmissio]

Maybe I'm missing/misunderstanding something, however, even after reading the documentation at https://besu.hyperledger.org/private-networks/how-to/configure/free-gas#update-hardhatconfigjs, I still fail to configure a free gas hardhat network.

That's my current hardhat.config.js:
module.exports = { solidity: { version: '0.8.20', settings: { evmVersion: 'london', optimizer: { enabled: true, }, }, }, network: { hardhat: { gasPrice: 0, gas: '0x1ffffffffffffe' }, } }

Can anyone provide a working example of a hardhat.config.js file that results in a free gas network?
