Test not passing even though code is correct and works

Tell us what’s happening:
In the lesson: Advanced Node and Express - Implementation of Social Authentication II
fCC’s tests all fail on this lesson even though the code is correct and the app behaves as expected when I do it manually. I also moved on the the next lesson (part III) which relies on this one and it passes without issues.
