Can't create/push action without any params

[DenisCarriere]

Smart contract example

#include <eosio/eosio.hpp>

class [[eosio::contract]] hello : public eosio::contract {
public:
    using contract::contract;

    [[eosio::action]]
    void world( ) {
        eosio::print( "hello" );
    }
};

❌ Can't push action with empty params

$ eosc -u http://localhost:8888 tx create hello world '{}' -p eosio    

ERROR: signing transaction: get_required_keys: Internal Service Error: Invalid packed transaction: Failed to deserialize data for hello:world: Failed to deserialize variant: Invalid transaction
