I have a discovery rule which pulls of a bunch of items . And then I have item prototype which pulls a json file for each discovered item.  using the item prototype as master key , i have created dependent items  to fetch values for each keys in json . 

Discovery Rule is working fine.

Item prototype is getting a json string for each discovered items .

{'name': u'CA-CCS', 'alert': 'NULL', 'state': u'NOT_STARTED', 'lastChangedStateTime': 'NULL', 'startTime': 'NULL', 'runtime': u'null'}

However, the dependent items for   each prototype are not getting created /working .

Response of each item prototype :
