I'm getting this error

Traceback (most recent call last):

AttributeError: 'NoneType' object has no attribute 'get_all_instances'

I am sorry. I did not pass start|stop|status as an argument. Now the script is running fine.

Prdeepprakhar, i am having the same issue, you have to pass start|stop|status as an argument? which line?
