I have a issue in FundMe.test.js

Issue: TypeError: no matching function (argument="key", value="provider", code=INVALID_ARGUMENT, version=6.6.3) #5867

this is my repo: https://github.com/abdulazizkhf123/fundme

just change any fundMe.provider.getBalance to ethers.provider.getBalance
and change address to target.
but I suggest you use ethersV5, to follow along with the lesson.

yeah, it worked but after that I have a this issue too, why it is happening ?
