##teamcity output when running tests using Guard Follow

When I start the Guard test runner from RubyMine 2020.1.3, the output consists of verbose messages in TeamCity format:

When I run ‘bundle exec guard’ in the terminal, it works fine.

I've dug through many of the issues that involve TeamCity and test output. I've also renamed my test files to follow the pattern ‘…test.rb’ instead of ‘test….rb’. – No luck.

My run configuration looks like this:

My Gemfile:

source "http://rubygems.org"

gem 'jeweler'
gem 'parslet'
gem 'test-unit'
gem 'minitest'
gem 'flexmock'
gem 'sanitize'

group :development do
gem 'guard'
gem 'guard-minitest'
end

My Guardfile:

guard :minitest do
  watch(%r{^test/(.*)\/?test_(.*)\.rb$})
  watch(%r{^lib/(.*/)?([^/]+)\.rb$}) { |m| "test/#{m[1]}test_#{m[2]}.rb" }
  watch(%r{^lib/guided_track/(?:content|attribute)_nodes/([^/]+)\.rb$}) { |m| "test/guided_track/nodes/test_#{m[1]}_node.rb" }
  watch(%r{^test/test_helper\.rb$}) { 'test' }
end
