Issue with namespaced resource

I'm running into difficulty with STI models and their corresponding resources.

I have a base model Event, with subclasses Events::Applied, Events::Interview (amongst others) and I'm not sure how to set up the resources. Currently I have an Api::V1::EventResource and Api::V1::Events::AppliedResource and Api::V1::Events::InterviewResource (both of which subclass the EventResource, however I'm getting an error NameError (JSONAPI: Could not find resource 'events/applied'. (Class Events::AppliedResource not found)) - it appears that my base namespace Api::V1 isn't being taken into account?

I'm also not sure how to handle model inheritance as a whole when it comes to JSONAPI::Resources. I'd like to have the base resource for index actions (immutable) and the subclass resources for create/updates (as well as index/show). Does this fit the pattern correctly? I'm certainly open to suggestions.

The issue names no files, tests, or entry points. Start by tracing JSONAPI::Resources resource lookup for the shown namespaced STI models and reviewing how inherited resources are resolved. Done means determining whether the namespace and inheritance arrangement is supported, or documenting the required resource setup and reproducing the result.
