Running Test for Get Entrance Fee Doesn't Work

I tried run my test for getEntranceFee function and got an error. I can't figure out whats going on here.

My test_lottery.py file :

from brownie import Lottery, accounts, config, network
from web3 import Web3

def test_get_entrance_fee():
    account = accounts[0]
    lottery = Lottery.deploy(
        config["networks"][network.show_active()]["eth_usd_price_feed"],
        {"from": account},
    )
    assert lottery.getEntranceFee() > Web3.toWei(0.018, "ether")
    assert lottery.getEntranceFee() < Web3.toWei(0.022, "ether")

my config file:

dependencies:
  - smartcontractkit/chainlink-brownie-contracts@1.1.1
compiler:
  solc:
    remappings:
      - "@chainlink=smartcontractkit/chainlink-brownie-contracts@1.1.1"
networks:
  mainnet-fork:
    eth_usd_price_feed: "0x5f4eC3Df9cbd43714FE2740f5E3616155c5b8419"

output error:
