Too large contract error

[Aamirusmani1552]

Hello everyone,
I am facing an issue while deploying my governance contract. I am currently at DAO's project from the course. when i am deploying my contract it is saying :
cannot estimate gas; transaction may fail or may require manual gas limit [ See: https://links.ethers.org/v5-errors-UNPREDICTABLE_GAS_LIMIT ] (reason="Transaction reverted: trying to deploy a contract whose code is too large", method="estimateGas", transaction={"from":"0xf39Fd6e51aad88F6F4ce6aB8827279cffFb92266","data":"0x6101606040523480156200001257600080fd5b5060405162007e593803

the whole error is to long but i mentioned here the reason that the error is giving me. I have also checked for the solution online and someone suggested to enable optimizer, so i did it but still having the same issue. Can anybody tell how to deploy contracts that are very large.

gas optimization setting i used in hardhat config:
settings: { optimizer: { enabled: true, runs: 200, details: { yul: false }, }, },

Hii @Aamirusmani1552, even I faced the same in your hardhat.config.js in config variable inside networks add this
hardhat.config.js

const config = {
    networks : {
+   hardhat: {
+			chainId: 31337,
+			allowUnlimitedContractSize: true,
+		},
+  localhost: {
+			chainId: 31337,
+			allowUnlimitedContractSize: true,
+		},
      }
}

You can also refer it here for configuration : https://github.com/technophile-04/onchain-DAO/blob/db3d6e664883aa58e7dde0189ac909a40b76f883/hardhat.config.ts#L27

Alternate (Patricks Code ) :
https://github.com/PatrickAlphaC/dao-template/blob/ba40040287fb17c75c9f58148f37fb80460c6af5/hardhat.config.ts#L20

We just need to tell it to allow unlimitedContractSize on local chain
