Hi everyone, I was having difficulty with lesson 7 (github discussion: #6237 ) and i decided to clone the lesson 7 project to reverse engineer it but even the cloned lesson 7 throws an error! I cloned the repo, ran "yarn", and updated the .env to my information. I then ran "yarn hardhat deploy --tags mocks" and it threw the error as seen below. I also then ran "source .env" and tried to run "yarn hardhat deploy --tags mocks" but it still didn't work.

So all in all, it's the lesson 7 cloned repo with an updated .env and it still does not deploy the mocks.

This is the error:

$ yarn hardhat deploy --tags mocks
yarn run v1.22.19
warning package.json: No license field
$ /home/smartchain/code/foundry-f23/fundme2/hardhat-fund-me-fcc/node_modules/.bin/hardhat deploy --tags mocks
Nothing to compile
failed to get chainId, falling back on net_version...
