thanks for the solution! I noticed that one close parenthesis is missing after enterRaffle():

 await expect(raffle.enterRaffle()).to.be.revertedWithCustomError(raffle,"Raffle__NotEnoughETHEntered")

[pratikbhangire123]

Ya my bad, corrected it :)

why doesn't revertedWith("Raffle__NotEnoughETHEntered") work anymore? I think we were using this in the fund me contract that way, but it's not working in Raffle, and we now need the revertedWithCustomError to get it to work now, did they change something recently?

[pratikbhangire123]

Well, I don't know exactly but I think it's because of the recent updates in Hardhat.
