Issue when testing using Appraisal for multiple gem versions

[uxxman]

Describe the bug
I am using simplecov on a ruby gem and testing via rspec. Everything works as expected. But when I add Appraisal and run test via **bundle exec appraisal rspec, code coverage report to codeclimate fails

Version of codeclimate-action you're using
v2.7.4
