Expected behavior

rubocop doesn't throws any exception or alerts.

Actual behavior

After updating rubocop-rspec gem (rubocop-rspec (1.42.0)) I got this alert in console:

3 errors occurred:
An error occurred while RSpec/FilePath cop was inspecting /.../app/channels/application_cable/channel.rb.
An error occurred while RSpec/FilePath cop was inspecting /.../app/channels/application_cable/connection.rb.
An error occurred while RSpec/FilePath cop was inspecting /.../app/controllers/application_controller.rb.
Errors are usually caused by RuboCop bugs.
Please, report your problems to RuboCop's issue tracker.
https://github.com/rubocop-hq/rubocop/issues

Mention the following information in the issue report:
0.89.1 (using Parser 2.7.1.4, rubocop-ast 0.3.0, running on ruby 2.7.1 x86_64-darwin19)

All this files are similar - they are empty and doesn't used at all:

app/channels/application_cable/channel.rb:

# frozen_string_literal: true

module ApplicationCable
  class Channel < ActionCable::Channel::Base
  end
end

app/channels/application_cable/connection.rb:

# frozen_string_literal: true

module ApplicationCable
  class Connection < ActionCable::Connection::Base
  end
end

app/controllers/application_controller.rb:

# frozen_string_literal: true

class ApplicationController < ActionController::API
end

when I run rubocop -d app/controllers/application_controller.rb, I got this trace:

An error occurred while RSpec/FilePath cop was inspecting /Users/ruslan/synergy/synergy-lms-api/app/controllers/application_controller.rb.

This issue is a dup with #999 and resolved by #1000. Can you update rubocop-rspec 1.43.1?
