Lesson 9: The first deploy, getting error " Cannot read properties of undefined (reading 'parseEthers') "

[darshilmistry]

This is the project repository :- https://github.com/darshilmistry/Lottery_FS.git

I have checked both of the deploy files but nothing came up. Also before this I removed all the yarn files and node_modules as i was getting some json rpc error.

The Errors are as follows:-

For yarn hardhat deploy :

[aaankeet]

In your helper-hardhat.config.js

change this : entryFee: ethers.util.parseEthers("0.3"),
to this: entryFee: ethers.utils.parseEther("0.3"),
for both networks

[Taha-Zerarkaa]

In ethers 6 you can use:

ethers.parseEther("")

instead of

ethers.utils.parseEther()

[Ebenezary]

The latest version of hardhat requires you to use :

ethers.parseEthers("insert figure here ")

instead of:

ethers.utils.parseEthers("insert figure here ")
