Lesson 6: Error when running deploy with brownie on sepolia network

[hodayaHammer]

I added sepolia with my infura api key to deploy my contract it works fine. Until I try to verify my contract with publish_source=True in FundMe.deploy function:

from brownie import FundMe
from scripts.helpful_scripts import get_account

def deploy_fund_me():
    account = get_account()
    # deploy makes a state change therefore we need to add {'from': account}
    fund_me = FundMe.deploy({"from": account}, publish_source=True)
    print(f"Contract deployed to {fund_me.address}")

def main():
    deploy_fund_me()

I get the following error:

  File "C:\Users\User\.local\pipx\venvs\eth-brownie\lib\site-packages\brownie\_cli\run.py", line 51, in main
    return_value, frame = run(
  File "C:\Users\User\.local\pipx\venvs\eth-brownie\lib\site-packages\brownie\project\scripts.py", line 110, in 
run
    return_value = f_locals[method_name](*args, **kwargs)
  File ".\scripts\deploy.py", line 11, in main
    deploy_fund_me()
  File ".\scripts\deploy.py", line 7, in deploy_fund_me
    fund_me = FundMe.deploy({"from": account}, publish_source=True)

    return tx["from"].deploy(
  File "C:\Users\User\.local\pipx\venvs\eth-brownie\lib\site-packages\brownie\network\account.py", line 557, in 
deploy
    contract.publish_source(deployed_contract, silent=silent)
  File "C:\Users\User\.local\pipx\venvs\eth-brownie\lib\site-packages\brownie\network\contract.py", line 408, in publish_source
    data = response.json()
  File "C:\Users\User\.local\pipx\venvs\eth-brownie\lib\site-packages\requests\models.py", line 975, in json    
    raise RequestsJSONDecodeError(e.msg, e.doc, e.pos)
JSONDecodeError: Expecting value: line 2 column 1 (char 1)

Has anyone seen this? Help needed asap!! thanks

Hello @hodayaHammer

First of all if you are using original contract code you should be passing price_feed argument while deploying. If you are able to deploy without verification question to you: Do you have ETHERSCAN_TOKEN described in your .env? It is necessary to verify contract
