Start with make_trade() in uniswap/uniswap.py, then follow the call into _token_to_token_swap_input() and _get_token_token_input_price() shown in the traceback. Reproduce the call against the reported WETH and APE pair and inspect the fee argument and pool lookup. Done when the cause is identified and the example either completes the swap or returns a clear explanation of the revert.

描述
Hello!
When trying to execute a swap using the make_trade() method I consistently get "web3.exceptions.ContractLogicError: execution reverted" error
This is the code that can be used to reproduce the error:
import os
from uniswap import Uniswap
weth_address = "0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2" # WETH
token_address = "0x4d224452801ACEd8B2F0aebE155379bb5D594381" # APE
uniswap = Uniswap(
address=os.environ.get('WALLET_ADDRESS'),
private_key=os.environ.get('WALLET_PRIVATE_KEY'),
provider=os.environ.get('PROVIDER_URL'),
version=3
)
tx = uniswap.make_trade(weth_address, token_address, qty=9000000000000000, slippage=0.3, fee=10000000)
print(tx)
Checking the APE/WETH pair on the Uniswap UI it seems to exist and also has good amount of liquidity.
Am I doing something wrong there?
Here is the full trace of the error:
