I ran brownie run scripts/deploy.py and received this error and I am unsure of what to do about it. Anyone have any suggestions ?

brownie networks list trueand show me the development network - Your entire deploy.py file.
Thanks

Lastly, my entire deploy.py file:
from brownie import FundMe, MockV3Aggregator, accounts, network, config
from scripts.helpful_scripts import (
get_account,
deploy_mocks,
LOCAL_BLOCKCHAIN_ENVIRONMENTS,
)
def deploy_fund_me():
account = get_account()
if network.show_active() not in LOCAL_BLOCKCHAIN_ENVIRONMENTS:
price_feed_address = config["networks"][network.show_active()][
"eth_usd_price_feed"
]
else:
deploy_mocks()
price_feed_address = MockV3Aggregator[-1].address
fund_me = FundMe.deploy(
price_feed_address,
{"from": account},
publish_source=config["networks"][network.show_active()].get("verify"),
)
print(f"Contract deployed to {fund_me.address}")
return fund_me
def main():
deploy_fund_me()
Note that although my deploy.py has changed since the time of the posting I still receive the same error.
Thank you for your time.
What happens when you run:
node --version
and
ganache-cli --version
?
When I run node --version I get:
v16.13.1
When I run ganache-cli --version
Ganache CLI v6.12.2 (ganache-core: 2.13.2)
