Lesson 6: Brownie Fund Me ValueError: insufficient funds for gas * price + value

[mvarenitsyn]

Hello everyone!

I'm trying to run a test script (test_fund_me.py) after establishing mainnet-fork-dev using Alchemy. Here is output:

def test_can_fund_and_withdraw():
account = get_account()
fund_me = deploy_Fundme()
print(f"my balance is {account.balance()}")
entrance_fee = fundme.getEntranceFee() + 100

  tx = fund_me.fundme({"from": account, "value": entrance_fee})

E ValueError: insufficient funds for gas * price + value

tests/test_fund_me.py:12: ValueError

What can be a reason? I also check for account balance:
Captured stdout call ----------------------------------------------------------------------------
Contract deployed to 0xE7eD6747FaC5360f88a2EFC03E00d25789F69291
my balance is 1000000000000000000000

Any thoughts?

UPD:
Same code passed well on ganache blockchain.
But on mainnet-fork-dev fund_me.getEntranceFee() function gives value = 238371441489773650809337480

Hello @mvarenitsyn
Go to ganache settings add setup a higher gas limit,
also be sure to have correct the getEntranceFee() function.
