I have a fresh rails-composer omniauth application. When running tests with rspec it gives this error:

It gives me much trouble to debbug.
EDIT. My gem file has those:
gem 'omniauth'
gem 'omniauth-facebook'
It is a fresh app generated with rails-composer, no custom code.
You should add require_relative 'helpers/omniauth' at the beginning of spec/support/helpers.rb - works for me.
