Issue with ActiveRecord association: "The Lap model class is not an ActiveRecord::Base subclass"

Question

I'm facing a strange issue with an ActiveRecord association in my Ruby on Rails project. When I try to access the laps association method from my User model, I get a peculiar error.

Error:

ArgumentError: The Lap model class for the User#laps association is not an ActiveRecord::Base subclass.

I've double-checked, and Lap is definitely a subclass of ActiveRecord::Base. I'm using Rails 7.1.3 and Ruby 3.2.2.

Here's the code for my User model:

class User < ApplicationRecord
  has_many :laps
end

And here's the code for my Lap model:

class Lap < ApplicationRecord
  belongs_to :user
end

I can't figure out why I'm getting this error. Has anyone else encountered a similar issue or have any ideas on how to resolve it?

I use

User.reflect_on_association(:laps).klass

what create an error but with the relation quiz has_many :laps and Quiz.reflect_on_association(:laps).klass

There is no errors in the 2nd case so I didn't understand why to similar code have different résult.
