      I have this default scope on one app:

      default_scope -> {
  all_of({'$or' => [{:maximum_uses => nil}, {:maximum_uses.gt => :uses}]},
         {'$or' => [{:expires_at => nil}, {:expires_at.gt => Time.now}]})
}

      For some reason, Model.first fails with the error in the title. Other methods, including Model.all, work perfectly. That's why I'm thinking this is a bug.

      Here's the stack trace:

      Any hints?
