I am trying to run the script in the terminal but I get this error TypeError: argument of type 'NoneType' is not iterable. Can anyone help me with this issue? Thank you in advance. Below is the entire code.

1.Get-weth.py

from scripts.helpful_scripts import get_account from brownie import interface, config, network

def main(): get_weth()

def get_weth(): """ Mints WETH by depositing ETH """

ABI&Address

account=get_account()
weth=interface.IWeth(config["networks"][network.show_active()]["weth_token"])
tx=weth.deposit({"from": account, "value":0.1*10**18})
print("Received 0.1 WETH")
return tx

2.Helpful-scripts.py from brownie import accounts, network, config

LOCAL_BLOCKCHAIN_ENVIRONMENTS = [ "development", "ganache", "hardhat", "local-ganache", "mainnet-fork", ]

def get_account(index=None, id=None): if index: return accounts[index] if network.show_active() in LOCAL_BLOCKCHAIN_ENVIRONMENTS: return accounts[0] if id: return accounts.load(id) if network.show_active() in config["networks"]: return accounts.add(config["wallets"]["from_key"]) return None
