Lesson 6: AttributeError: Contract 'FundMe' object has no attribute

[BrysonHall]

I was doing the Patrick Collins tutorial link and I got this error: "AttributeError: Contract 'FundMe' object has no attribute 'account when running brownie run scripts/deploy.py --network rinkeby

Help is much apricated 🙂

My code:

deploy.py

 from brownie import FundMe
 from scripts.helpful_scripts import get_account


def deploy_fund_me():
    account = get_account()
    fund_me = FundMe.deploy({"from": account})
    print(f"Contract deployed to {fund_me.account}")


 def main():
     deploy_fund_me()

Hello @MrHeim1
You have this line:
print(f"Contract deployed to {fund_me.account}")

A contract does not have something called account, you may be referring to address?

print(f"Contract deployed to {fund_me.address}")
