TypeError: Cannot read property '0' of undefined

I'm having the issue below and can't seem to get around it. I'm using a custom .csscomb.json file I built from the CSScomb website, but I don't think that has an impact on this issue because when I remove the file the issue still occurs. Seems to be an issue with the plugin itself. I'm surprised nobody else has seemed to have this issue, other than a couple links I found where 1 person had a similar issue and then Tony addressed it with a fix. If you could help shed some light on what I might be doing wrong or how it can be addressed that would be awesome. Thanks!

I hope the author will read the message and correct the error

Can you run it with a debugger and check what does it pass to csscomb.processString() method? You can put a breakpoint here: https://github.com/koistya/gulp-csscomb/blob/efec3a1c70ac307fdd04e62203f3d96c2ad2df98/index.js#L65
