Refinements not working in Endeca Studio Cluster under "Available Refinements".

Endeca server and Studio in cluster have been configured per <Note 2214433.1> "Oracle E-Business Suite Information Discovery Clustering Guide, Release 12.2 V8"

This Endeca is integrated with EBS R12.2.7. EBS PO-Proc command center is linked with Endeca.

When accessing command center from "Project Procurement (Buyer)" EBS responsibility then it calls Endeca Studio to display the data.

It was working fine with Single Node Studio. When clicking on any refinments under "Available Refinements", a circle image icon displays and spins forever, it does not finish with timeout error or any error message

It does not show data in dropdown list and stop responding. After that if clicking on on any tab or link it does not respond.

Below error message appears in Studio log.
