ethers smart-contract blockchain hardhat test 智能合約時，透過ethers.getSigners()建立Signer並使用
跑 npx hardhat test 發現問題：Error: invalid address or ENS name (argument=”name”, value=”<SignerWithAddress 0xf39Fd6e51aad88F6F4ce6aB8827279cffFb92266>”, code=INVALID_ARGUMENT, version=contracts/5.6.0)
把alice使用console.log印出來看看
把 {from: alice} 改成 {from: alice.address}
Problem solved!
