@Bhavik-punmiya Check your helper file, Are you using ethers there? If yes then make sure you import the ethers there.

@Bhavik-punmiya main waffle package was missing in hardhat config file

require("@nomiclabs/hardhat-waffle")

and here tags had typo;

module.exports.tags = ["all", "frontend"]

[alymurtazamemon]

@Bhavik-punmiya Also the project is outdated move it to hardhat-toolbox plugin now, you can read the guide here #Migrating away from hardhat-waffle

[Bhavik-punmiya]

Thanks @alymurtazamemon the code is running fine now but I am little confused few days back I have ask another query
https://github.com/smartcontractkit/full-blockchain-solidity-course-js/discussions/5571#discussioncomment-6037420 in this you said migrate away from hardhat waffle , so I did that will it make any difference if I add it again

[alymurtazamemon]

@Bhavik-punmiya Yes, here I am saying that too!

[Bhavik-punmiya]

Yesss ! Thank you @alymurtazamemon it works fine now 🥲
