'`result_exit_status': undefined method `-' for nil:NilClass (NoMethodError)
I am trying to add the Code Climate Test Reporter to a New Rails app that we are currently building.
I have setup circleci on other projects so I modified the config to suit this project but I continue to get the following error when the rspec tests finish running.
69 file(s) with 100% coverage not shown
Traceback (most recent call last):
3: from /home/circleci/my-app/vendor/bundle/ruby/2.7.0/gems/simplecov-0.17.1/lib/simplecov/defaults.rb:29:in `block in <main>'

Exited with code exit status 1
CircleCI received exit code 1
Have anyone seen an error like this? If so, any suggestions for getting the Code Climate Test Reporter to work correctly with CircleCI?

Solution 1:[1]
I had the same issue. I figured it out. Deleting my coverage folder resolved the problem for me. (It'll be created again the next time you run SimpleCov.)
Here's why that solved the problem:
I previously installed a newer version of SimpleCov in order to try out branch coverage (which CodeClimate does not yet support). So, when I switched back to version 1.17.1 to be CodeClimate compatible, the file coverage/.last_run.json contained JSON that did not match the expecations of SimpleCov 1.17.1. So, deleting the file (and the whole folder for good measure) allowed SimpleCov 1.17.1 to recreate it in a format that it understands.
Here's how I figured it out:
I ran bundle open simplecov which opened the gem source code in my editor. I then went to the line where the error occurred (simplecov.rb:243), and added a puts statement to see the value of the hash in the last_run variable. The results were missing the covered_percent and instead included branch coverage information, something version 1.17 does not support.
