Research direction
Start at lib/jsonapi/processor.rb:587 and reproduce the failure with GET /uuids/3bbaf722-4583-4fa6-ac36-9190d4b93f80?include=ids using the UuidResource and IdResource definitions in the issue. Trace how resource_set keys are created and accessed, then verify that the request completes without the undefined method [] error and includes the associated ids.

Description
I've tracked the issue to lib/jsonapi/processor.rb:587.
resource_set[resource_klass] is holding the associated resources in an array key'd by a string {"1" => [...]} and attempting to access it via an int resource.id.
With the following resources just issue this get request (make sure to have include=).
GET /uuids/3bbaf722-4583-4fa6-ac36-9190d4b93f80?include=ids
class UuidResource < JSONAPI::Resource
key_type :uuid
has_many :ids
end
class IdResource < JSONAPI::Resource
has_one :uuid
end
Throws error:
