I had to bump the verison of solidity in the hardhat config to get this to work. It may be because there is a package-lock.json but the readme says to use yarn, so it may install a newer version as a dep.

hardhat.config.js

module.exports = {
  solidity: "0.8.9",
  networks: {
    local: {
      url: 'http://localhost:8545'
    },
    goerli: {
      url: 'https://rpc.goerli.mudit.blog',
      accounts: [process.env.PRIVATE_KEY],
    },

  }
};

Even with that change I can't make it work. Should I bump solidity to a newer version?

You should do what @kylemantesso said in the previous response (https://github.com/OpenZeppelin/workshops/issues/28#issuecomment-1291138261) and then compile!

yarn hardhat compile

Or at leas that worked for me. Then, if you are deploying the Forwarder/Registry contracts with your relayer you should found the relayer with goerli eth after compiling!
