If you're using the supported version of Angular and 0.6.1 still fails, please create a minimal reproduction. I.e. create a new Angular CLI project, add minimal code to reproduce the problem, push it on GitHub and post a link here. Without this reproduction there is nothing we can do to resolve this issue.
Describe the problem
The screen doesn't launch because of the NullInjector Error, in production mode when the modules are loaded lazily.
What did you expect?
To work properly like older version, We downgraded it to 0.5.0 and it works.
