After tests of PnP PNF scenario we discovered that  SO (BPMN app) looks for data from PRH at wrong DmaaP topic.

Query happen on /events/pnfReady/consumerGroup/consumerId  topic and looks for message:

["\\\\{\"pnfRegistrationFields\":{\"correlationId\":\"NOK-d3a844a134a1sl4fg43d3kls2\"}}"]

However is should query on topic:

/events/unauthenticated.PNF_READY/consumerGroup/consumerId and look for following message

*["

{\"ipaddress-v4-oam\":(\"13.13.13.13\",\"ipaddress-v6-oam\":\"2001:0db8:0:0:0:0:1428:57ab\",\"correlationId\":\"NOK-d3a844a134a1sl4fg43d3kls2\"}

"]*

 

Remarks: Issue occurs only in workflow dedicated for PNF PnP use case. It doesn't influence standard SO workflow.
