Missing "addressSpace" key value for private subnet

[manojgudi]

For a virtual machine(box):
way to reproduce this is for a box with 2 IPs (Private + Public)

client  = SoftLayer.create_client_from_env()
vsmgr = SoftLayer.VSManager(client)
instanceDetails = vsmgr.get_instance(INSTANCE_ID)
componentList = instanceDetails.get("networkComponents")
# This should print "PRIVATE" and "PUBLIC" respectively, instead one of the output is None, i.e. private network component dictionary has no key/value "addressSpace"
for i in componentList:
    print( i["primarySubnet"].get("addressSpace") )

Expected Behavior

PRIVATE
PUBLIC

Actual Behavior

None
PUBLIC
