Data Analytics Server 3.1.0 throwing exceptions

I am using WSO2 API Manager 2.0.0 & WSO2 DataAnalyticsServer 3.1.0.
I have made the following configurations:

  1. Enabled Analytics in api-manger.xml
  2. Directed it to my DAS Server Port
  3. Added DAS_AGENT to log4j properties

The servers started properly
In DAS' management console, I uploaded the APIM_Realtime_Analytics.car All this was in accordance with : https://docs.wso2.com/display/AM200/Running+the+Product#RunningtheProduct-AccessingtheManagementConsole https://docs.wso2.com/display/AM200/Configuring+APIM+Analytics docs.wso2.com/display/DAS310/Quick+Start+Guide

But I am getting the following error:

Since the server wasn't getting certain Stream Definitions,
I also tried deploying APIM_Realtime_Analytics_REST.car(from a previous version of DAS) but to no avail. I'm getting similar exceptions for that

How do I rectify this?
Thanks in advance!

As mentioned in the document you are referring to, now APIM has its own Analytics Server, which is a customized DAS. So now you have a very few configurations to do to see API stats. That distribution already has required CApps installed too. So you don't need to install them manually.

But, as I understand, you are using a vanilla DAS Server instead of APIM Analytics Server. If possible, please try with that. If you can't for some reason, take the car file from that distribution and install it in DAS. That should solve your issue.
