Unsupported OS/browser/version/device combo: OS: 'unspecified', Browser: 'iphone', Version: '8.4.', Device: 'iPhone Simulator'

My tests were working fine then stopped working without making any changes to the code. I started getting the error below. Since first getting the error I have tried changing the versions and devices but still can’t get past this. Your help is appreciated.
Ruby: 2.1.3
appium_console: 1.0.4
appium_lib: 7.0.0
iPhone Simulator: 8.4
xcode: 6.4

Thanks @bootstrap
As I wrote in my post the version and OS were supported.

The issue was with installing appium_console via Gemfile. It did not seem to like it installed that way. I went ahead and reinstalled using the steps provided on github to fix the issue:

gem uninstall -aIx appium_lib ;\
gem uninstall -aIx appium_console ;\
gem install --no-rdoc --no-ri appium_console bond
