On an html page there’s an input with a certain id.
use Wallaby.DSL

{:ok, session} = Wallaby.start_session()
visit(session, "some_url")
|> fill_in("#some_id", with: "Test1") # 1
#    |> fill_in(Query.css("#some_id"), with: "Test1") # 2

This throws an exception:

 ** (FunctionClauseError) no function clause matching in Wallaby.Browser.find/3
            (wallaby) lib/wallaby/browser.ex:444: Wallaby.Browser.find(%Wallaby.Session{driver: Wallaby.Phantom, ....

And the # 2 gives this exception:

** (Wallaby.QueryError) Expected to find 1, visible element that matched the css '#some_id' but 0, visible elements were found.

The element-input with id “some_id” exists on a page and is visible.

What can be the matter and how to fix that?
