Michael Mokry - can you take a look at this and help? I suspect he is querying for policies that don't exist or haven't been pushed.

The issue was caused by the PDP failing to register during initialization, so the policies were not pushing and the PDP was not loading the pre-configured policies in the PDP file system (xacml.policy.properties). I am not sure why it failed to register with the PAP, historically this issue is related to a db issues or missing/invalid properties in the properties file. Further analysis into catalina logs should print out a whole log trace if there are any errors so Sudhakar could look at this if the issue occurs again. We resolved the issue by simply restarting the PDP so it would register with the PAP and then restarting the PAP to run the audit code in the init() that updates the PDP group in the file system to be in sync with the DB.

Hi,
I'm trying to access the getConfig API which is used in DCAE poilcy handler to identify the working.
Here's the request I'm using:
curl -v -X POST --header 'Cont cHl0aG9uOnRlc3Q=' --header 'Authorization: Basic dGVzdHBkcDphbHBoYTEyMw==' --header 'Environment: TEST' -d '{ "policyName": ".*"}' 'http://pdp:8081/pdp/api/getConfig'
The response I'm getting is:
[{"policyConfigMessage":"No Response Received","policyConfigStatus":"CONFIG_NOT_FOUND","type":null,"config":null,"policyName":null,"policyType":null,"policyVersion":null,"matchingConditions":null,"responseAttributes":null,"property":null}]
In PDP logs, it is showing Null pointer exception. By static code analysis, I guess decide method in Policy is throwing the error. The logs are as below:

I want to understand when I update policy (Threshold values of MS policy) and pushed to PDP, how DCAE will get the latest threshold values so that it'll store in dcae-config. Also, whether this error is going to effect the closed loop flow.
