InvalidOutputType("Expected single element, got an empty list")

[sergeyT2]

Hey everyone,

referencing this, obiously #115

The contract I'm querying doesn't have explicit return value. Therefore I'm getting an error of
InvalidOutputType("Expected single element, got a list: []")

How do I type it correctly? web3::contract::Result of something?

Provide a PR for this: #656

The no-value return type is (), have you tried that?

Yeah, it says trait web3::contract::tokens::Tokenizable not implemented for ()

[sergeyT2]

@tomusdrw anything happening?

Do you mind providing a full example? I don't think parsing an empty value into an empty list as proposed in #656 is the correct behavior.
