The actual root cause of the issue was, the
"Adobe Granite Workflow Corecom.adobe.granite.workflow.core)" bundle was stapped.
The restart also not helped, the bundle was not started on server restart.
The issue got resolved after manually starting the bundle - "Adobe Granite Workflow Corecom.adobe.granite.workflow.core)"
