[BUG] Type 'felt252' is not defined error when using starknet.py

[otatataata]

What happened

Hello,

I am encountering an issue when trying to use the starknet.py library with a smart contract that utilizes the felt252 type.

API I'm using: https://github.com/influenceth/sdk/blob/master/src/contracts/starknet_events.json

With the function ExtractResourceFinish

     function_name = "ExtractResourceFinish"
        call_data = [
            5,  # extractor (Entity converti en felt)
            5,  # extractor_slot (u64)
            6410  # caller_crew (Entity converti en felt)
        ]

Steps to reproduce

from starknet_py.contract import Contract

Assuming ABI data is loaded from a source, here represented as a dictionary

abi_data = {
'name': 'ExampleFunction',
'type': 'function',
'inputs': [{'name': 'example_input', 'type': 'felt252'}],
'outputs': [],
'stateMutability': 'external'
}

contract = Contract(address="0x0422d33a3638dcc4c62e72e1d6942cd31eb643ef596ccac2351e0e21f6cd4bf4", abi=[abi_data])

Hey @otatataata, thanks for report. Could you please provide full code sample? This way I will be able to reproduce the error. Also, v0.4.7 is a very old version of the SDK. Did you try to use a newer version?
