@anorborg I've had a few folks report this and they forgot to CD to the project directory. Are you still able to reproduce this problem?

I am facing an issue when i CD into the project directory. Any pointers to resolve it? Error:: Selected Code Generator: identity No code generator found with the name 'identity'.
