A user of mine noticed that the watchlist was blank and after a few debugging, I noticed that the v4 Watchlist API was returning a null value instead of the movie. My guess is the movie was added to the watchlist and then was deleted from the database entirely. This has an impact on the website as well as the list is hidden when that item is within the array.

Here is the response from the watchlist (notice the null item in the array):
