I am trying to integrate the IBM Application Security on Cloud (ASoC) with Jenkins by using the "IBM Application Security on Cloud Plugin". I have successfully installed Plugin in Jenkins and restarted Jenkins.

While adding "Run Security Test" build step details in a job, after selecting Credentials (as defined on Jenkins Credentials page), I'm getting an empty list in Application drop-down and don't know reason for that.

Note:

1. As a pre-requisite, I have created an application in the IBM Application Security on Cloud.  
2. I have added ASOC API credentials in Jenkins Credential page by generating key id and secret key from ASOC app.
3. I'm using trial version of ASoC found on IBM Marketplace.

Below are the Jenkins Err logs
