@sparrow313 : Correct your this line of code with this one: const wethBalance = await iWeth.balanceOf(deployer)

You were missing await keyword, That's why it is giving you error "Invalid Signer", Rest your code is fine.

Thanks a lot, my friend. It works

Hey @sparrow313 add await on line 15 and if it still doesn't work, reinstall your node modules.
