Decoder class for "sp_weights::weight_v2::Weight" not found

See original GitHub issue

Hello! For some networks, when I try to substrate.get_payment_info(call=call, keypair=test_keypair) it falls down with error: Decoder class for "sp_weights::weight_v2::Weight" not found

Shortest code to reproduce it:

from substrateinterface import SubstrateInterface, Keypair

url = "wss://karura-rpc.dwellir.com"

substrate = SubstrateInterface(url=url)
test_keypair = Keypair.create_from_uri('//Alice')
call = substrate.compose_call(
    call_module='Balances',
    call_function='transfer',
    call_params={
        'dest': test_keypair.ss58_address,
        'value': 0,
    }
)
substrate.get_payment_info(call=call, keypair=test_keypair)

Environment: ❯ python --version Python 3.11.0 substrate-interface==1.4.0

Otherwise you can try to add a type with that name manually to the type registry, but it needs some knowledge of custom types
