I was running into the same issue, and your post helped me out.

Looks like a quoting issue. I’ve escaped some of the double-quotes and switched to single quotes inside the dictionary. Maybe try this:

test-module -m /usr/share/ansible/monitoring/my\_maintenance.py -a “schedule\_type=One-Time devices="{‘hostName’:‘HYDLPT326’}" start\_time=2015-06-01T16:00:00+0000 end\_time=2015-06-01T16:30:00+0000 timezone=‘Asia/Calcutta’ client\_id=client\_2655”

I was missing the double-quotes around the dictionary.

Good luck!
