Example does not compile (Elm 0.19.1)

[llaisdy]

Here is the error:

elm-form$ cd example/
example$ elm make src/Main.elm --output main.js
Detected problems in 1 module.
-- TYPE MISMATCH ------------------------------------------------- src/Model.elm

This function cannot handle the argument sent through the (|>) pipe:

147|     succeed Profile
148|         |> andMap
149|             (field "website"
150|                 (oneOf
151|                     [ emptyString |> map (\_ -> Nothing)
152|                     , validateUrl |> map Just
153|                     ]
154|                 )
155|             )
156|         |> andMap (field "role" (string |> andThen (includedIn roles)))
157|         |> andMap (field "superpowers" validateSuperpower)
                ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The argument is:

    Field
    -> Result
           (Error.Error CustomError)
           (List Superpower -> Int -> String -> Profile)

But (|>) is piping it to a function that expects:

    Validation CustomError (Superpower -> b)

The code also seems not to be the code for the live demo (e.g. Model.initialFields has age = 33 and a list of todos).
