Loot Tables for Entities not working

I am trying to get Cod to drop an item. Currently, I have it set to where it should drop the "Golden Fish" item every time I kill one, but it won't work. I've tried Data Merges, but it could be outdated. Here's the generated code: (Keep in mind, I'm fairly new to MCCreator, and I don't really get loot tables.) Thank you!
