Lesson 6: TypeError: argument of type 'None Type' is not iterable

[klewist4]

Hello,

I am trying to complete lesson 6 and am about 5 hrs 15 min into the video: https://www.youtube.com/watch?v=M576WGiDBdQ&t=362s.

I am running this command prompt: brownie run scripts/deploy.py --network rinkeby (I have also tried brownie run scripts/deploy.py) BUT I am getting this error:

File "brownie/_cli/main.py", line 64, in main importlib.import_module(f"brownie._cli.{cmd}").main() File "brownie/_cli/run.py", line 42, in main active_project.load_config() File "brownie/project/main.py", line 462, in load_config _load_project_config(self._path) File "brownie/_config.py", line 222, in _load_project_config and "cmd_settings" in values TypeError: argument of type 'NoneType' is not iterable

Here is my deploy.py:

from brownie import FundMe from 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.address}")

def main(): deploy_fund_me()

And my brownie-config.yaml:

Can someone help me understand what I might be doing wrong here, or where the issue lies? Thank #you!

Why is there a backslash in your file path: scripts\deploy.py? Shouldn't it be scripts/deploy.py?

[klewist4]

Hey sorry, to confirm I've tried both ways. But you're right, it should be the latter. Either way - doesn't work :( Any other thoughts or suggestions?

Brownie parses the networks part in brownie-config.yaml in a certain way that you cannot put an existing network id (in brownie networks list) and let it empty.

networks:
  rinkeby:

-> error

networks:
  rinkeby:
    test:

-> no error

But I think the best would be not to put the networks you don't use yet

I'm having this error too

7xAquarius, you were right, TYSM
