Configuration variables causing compilation errors with plugin by NerdyPuzzle

I am already a bit deep into making a mod with various features, using various plugins, and I was trying to add a system to detect mobs that should be categorized as arthropods but aren't. To do this, I used the Configuration Files plugin by NerdyPuzzle and added to my config file variables arthropod_list and arthropod_filter, which are then referred to when a specific projectile hits an entity and is supposed to deal AoE damage to nearby mobs that fit the criteria. After adding those two variables, trying to run the game or regenerate code gives me a compilation error message.

Does anyone have any ideas for how this could be fixed, or do I simply have to not include my arthropod detection system because it will inevitably make the mod non-functional?

Also I wanted to include the workspace file here so that anyone can see what exactly it is I'm dealing with, but I don't see an option to embed files. How can I share the file here? Do I need to upload it elsewhere and link it?
