I just went through the Sum Numbers challenge, and the extra test seems bugged somehow? I passed all the initial tests, and it complains that `sumNumbers("It is the natural number following 4 and preceding 6 and is a prime number")` returns null, but when I test it in the console, it definitely returns 10, which is expected.
