Error adding TV show to watchlist: Cannot get property 'id' of null object

[johnsmith1232541]

Issue description

After creating a TV show, I cannot add the TV show to watchlist, it gives an internal server error and the entire StackTrace is below.

A very important detail is that adding to watchlist is fully functional with movies, just not with TV Shows. After inspecting the request to /watchlistEntry/create.json I have found absolutely no difference except for the different id and mediatype, but they're being passed in the same way.

Steps to Reproduce

1. Create TV show
2. Add TV show to watchlist
3. ERROR

StackTrace

ERROR org.grails.web.errors.GrailsExceptionResolver - NullPointerException occurred when processing request: [POST] /watchlistEntry/create.json
