AttributeError: 'approve' object has no attribute 'build_transaction' #312

Hi! Trying to use v3 on Polygon to swap MATIC/USDC. Running into the error in the title (full copy below), Using the latest version of Uniswap Python.

I am able to use get_eth_balance() and get_price_impact just fine, but make_trade runs into the error below.

from uniswap import Uniswap
import config
from web3 import Web3
from web3.middleware import geth_poa_middleware

web3 = Web3(Web3.HTTPProvider(config.node_address))
print("Connected to Polygon Node: ", web3.isConnected())

web3.middleware_onion.inject(geth_poa_middleware, layer=0)

address = config.my_wallet_address
private_key = config.my_private_key
version = 3
provider = config.endpoint
uniswap = Uniswap(address=address, private_key=private_key,
                  version=version, web3=web3)


print(uniswap.get_eth_balance())  # works fine

print(uniswap.get_price_input(config.matic_address,
      config.usdc_address, 10**18))  # works fine


uniswap.make_trade(config.matic_address,
                   config.usdc_address, 10**18, fee="500")
