Error running yarn hardhat deploy

[waner11]

When I finished the script 03-deploy-governor-contract and try to run the deploy command, it throws the error below, I have the exact same code shown in the YT tutorial. The first two contracts are deployed but the error comes in the third one, the GovernorContract.

Error: 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"

Hey mate!
I had the same problem and I was able to fix it by changing this in hardhat.config.ts:
Change this line : solidity: "0.8.8", for:

  solidity: {
    version: "0.8.8",
    settings: {
      optimizer: {
        enabled: true,
        runs: 200,
      },
    },
  },

I hope it helps 🙂

Can you make a PR with this? 🙏

@PatrickAlphaC I just realized this piece of code was already included by @zeuslawyer here: d2afede#diff-57cf5378f8cab20b02b279097ba6fad08eb53f747d81770045dda9c5f95effe3
