RubyMine Remote SDK with docker-compose finds and sets up correctly, but terminates the rspec

Question

I have set up docker-compose with my SDK, as per the IntellJ Instructions, and it found and indexed the gems. Shows the list, and log states that it is installing. However when I go to run the specs, I get the following error.

/usr/local/rvm/rubies/ruby-2.6.5/lib/ruby/site_ruby/2.6.0/rubygems.rb:265:in `find_spec_for_exe': can't find gem rspec-core (>= 0.a) with executable rspec (Gem::GemNotFoundException)
from /usr/local/rvm/rubies/ruby-2.6.5/lib/ruby/site_ruby/2.6.0/rubygems.rb:284:in `activate_bin_path'
from /usr/local/rvm/gems/ruby-2.6.5/bin/rspec:25:in `<main>'

I know that the gems are installed in the docker image, but I feel like either it's not running bundle exec in the proper directory.

The docker-compose will also run the tests from the CLI.

I feel like there is some setting that isn't correct.

I have changed the build configuration to run in the proper directory ( it's a standard rails app nested in a parent directory )
