Steps to Reproduce


Root Cause

A software use or operation error. Nodes are configured in the Stream landing page. A single Stream node is required and the users must add two Stream nodes in case of the High availability environment.


Perform the following local-change:
Configure a Stream node in the Stream landing page by navigating to Decisioning > Infrastructure > Services > Stream.
