Answer 1

I'm guessing something is going wonky with the regexp compile. It supposed to use Regexp.escape(source) but something might be slipping through? Please include the full error output though.

Answer 2

After a deep investigations, we have found the root cause of the issue. The name of the Github repository was interpreted by Chef as an escape character (the name of repository was starting with capital letter "C") which caused the configuration to fail alternately.

It regards to Chef 12.0.3 version (I hope, they fixed it in a newer next version)

We changed the name of repository and it solved the problem.
