Error parsing function that takes input as a struct. #102

Closed sarinniural closed 1 year ago

sarinniural commented 1 year ago

I am trying to use the decoder, but it fails with the exception as follows. Maybe this can help https://github.com/ethereum/web3.py/pull/2211

ABI is here https://goerli.etherscan.io/address/0xADF688869E47D404af9aaD295e09Efa06bbAD593#code

def parse_function(input):
    decoder = InputDecoder(abi)
    result = decoder.decode_function(input)
    print(result)

I figured out that the issue happens if I have the web3 dependency pip installed. Removing web3 and installing this package again resolved the issue

Probably caused by eth-abi or eth-utils version discrepancy. Glad you have solved it :)
