I have same problem. I have extracted first 8 character for contract method. But some transaction have got error

if data[:8] == "a9059cbb":
text = trx_abi.decode_abi(['address', 'uint256'], bytes.fromhex(data[8:]))
print(text)
elif data[:8] == "23b872dd":
text = trx_abi.decode_abi(['address', 'address', 'uint256'], bytes.fromhex(data[8:]))
print(text)

I change to use to_base58check_address for decode and it works
