Hi!
I have a problem with ExW3.Contract.call method and ABI.TypeDecoder.decode_type.
Solidity function:
function get_DFA(uint dfaID) public returns (DFA memory) { DFA storage dfa = dfa_pool[dfaID]; return dfa; }
Elixir function:
def sc_call(sc_abi_path, sc_address, sc_name, sc_method, sc_method_args \\ []) do
ExW3.Contract.start_link()
sc_abi = ExW3.Abi.load_abi(sc_abi_path)
ExW3.Contract.register(String.to_atom(sc_name), abi: sc_abi)
ExW3.Contract.at(String.to_atom(sc_name), sc_address)
ExW3.Contract.call(String.to_atom(sc_name), String.to_atom(sc_method), sc_method_args)
end
When I call this method from ElixirApp, I get a error
ElixirApp.Utils.Ethereum.sc_call("data/DFAPool.abi", "0x39Df1178CCBeC6d48A81969b6f67f13F3B4CC6E3", "DFAPool", "get_DFA", [1])

I don't understand what's happened.
