After updating to current versions, CI started throwing errors like:

An error occurred while loading ./spec/unit/shoulda/matchers/action_controller/filter_param_matcher_spec.rb.
Failure/Error: require environment_file_path

NameError:
  undefined method `=~' for class `Pry::Code'

Fixed after changing versions of pry-byebyg/pry.

PS: The error in the CI now is caused by a intermitent test. I'm going to work on it.
