Testing Elixir: Wrong spec for `parse_response/1` (page 5)

This one had me second-guessing myself, but I’m fairly certain this is an error in both the book’s code sample and the provided source:

@spec parse_response(Weather.t()) :: {:ok, list(Weather.t())} | {:error, atom()}

This function is supposed to take the erlangified response from the API, which should just be a raw map that ultimately comes from Jason, not the %Weather{} struct. That’s how it is used in the following test, and in the project source.
