@ippy1997 : Change the following line of code in your 01-deploy-raffle.js file :

From this : const VRFCoordinatorV2Mock = await ethers.getContract("VRFCoordinatorV2Mock.sol")

To this : const VRFCoordinatorV2Mock = await ethers.getContract("VRFCoordinatorV2Mock")

Contract name in getContract should be VRFCoordinatorV2Mock

Let me know, If it resolves your issue!

can you tell how i can push my code in a repo , from VS code in the command line , because its always confusing

RoboCrypter Sep 15, 2022

@ippy1997 : Of course : Follow the steps and run the following commands in the given order :

First Create a new repository in your github account, In order to push your code to that repository, It will provide you a link

Then go to your VS code terminal and write the following commands in order:

git init
git add -A
git commit -m 'first commit'
git branch -M main
git remote add origin YOUR REPO LINK Paste that link in the place of YOUR REPO LINK
git push -u origin main
