I am writing my first test with pact and it seems I am running into a problem.

(pact_erlang 0.2.2) :pactffi_nif.given(65537, %{params: %{foo: "bar"}, state: "foo"})

I have those actual values in the given expression. I am getting an argument error. That map would be

#{params => #{foo => <<"bar">>}, state => <<"foo">>}

in Erlang. Any help here would be appreciated.
