@fatihpehlvan Your mocks deploy script looks correct. Please leave your repo link so I can test it and let you know the reason. |

@fatihpehlvan Hey, The main issue due to that you are facing is the ethers version. You are using the latest version of ethers which has many big updates and because it is updated very recently I also haven't read the latest updates. I would recommend you to use the same version of ethers which is defined in the repo's package.json file. Not just ethers but all others you should use the same while learning so your learning process can be smooth and later you can use the updated versions to enhance your knowledge. In addition to that, you have other minor issues as well in 01-deploy-raffle.js file, such as you specified hardhat before this

I updated but don't forget to downgrade versions. My problem was about ethers package was 6. Make sure your ether (and other packages) same as mine or the same as instructor's. |
