What's this?

raise_record_not_found_exception!(ids = nil, result_size = nil, expected_size = nil, key = primary_key) public

This method is called whenever no records are found with either a single id or multiple ids and raises an ActiveRecord::RecordNotFound exception.

The error message is different depending on whether a single id or multiple ids are provided. If multiple ids are provided, then the number of results obtained should be provided in the result_size argument and the expected number of results should be provided in the expected_size argument.
