After several hours of research in trying to figure out how I can register a new task, update service & register task in my pipe line. I found this. never used lambda before. This helped me get started and solved all my problems. Thank you for your post!

Thank you, from two years in the future. I was just about to write a lambda like this but googled instead on a whim.
