Lesson 6: HardhatError: HH700: Artifact for contract "SimpleStorage" not found.

I'm getting this error when running yarn hardhat run scripts/deploy.js:

yarn hardhat run scripts/deploy.js

run yarn hardhat compile first then try running your script again.

I already tried that before, still the same

yarn hardhat compile
yarn run v1.22.15
warning ../../package.json: No license field
$ /Users/myusername/hh-fcc/hardhat-simple-storage-fcc/node_modules/.bin/hardhat compile
Nothing to compile
✨  Done in 0.89s.

make sure this line contains the correct name of your contract.sol file

const SimpleStorageFactory = await ethers.getContractFactory(
          "SimpleStorage"
     )

Make sure the spelling and wording is the same as the contract in your .sol file.

If is still fails, post your code to github and leave a link here, I'll look into it.

Delete node_modules, cache and artifacts.

Then, do yarn install followed by yarn hardhat compile.

If the problem still persists, please push to GitHub and I will look into it.

Hi guys, actually I deleted everything and started from scratch again.
Turns out I forgot to copy the SimpleStorage.sol code into the SimpleStorage file. It still had the Greeter.sol code in there.
Thanks for your help

Uh oh.. please be attentive next time.

All the best!!

Glad it worked out. Be keen next time :)
