                function = Keyword.get(options, :function)
          
                case call_function(function, value, context) do
                  {:error, reason} ->
                    {:error, reason}
          
                  falsy when falsy === false or falsy === nil ->
                    {:error, message(options, "must be valid", value: value)}
          
                  _ ->
                    :ok

            defp call_function(f, value, _context) when is_function(f, 1), do: f.(value)
            defp call_function(f, value, context) when is_function(f, 2), do: f.(value, context)
          end

It accepts function of arity 1 or 2 - if it is 2 it is passing context as second param.

You might have to relook at your test function
