Rubocop-rspec: RSpec/FilePath error occurs in 1.43.0

[steiley]

After changing rubocop-rspec version to 1.43.0, I got the following error.
It may be some kind of bug, so we would appreciate it if you could fix it.

bundle exec rubocop -d app//channels/application_cable/channel.rb
An error occurred while RSpec/FilePath cop was inspecting /app/app/channels/application_cable/channel.rb.
