Error 500 Internal Server Error on the controller

[Sai.Kiran]

I have trail veriosn of appdynamics and want to use Appdynamics to benchmark the application performance for my  MYSQL Database.

In my contoller,I was able to add Database Agent and  database collector through UI.

I was not able to add the same Databse collector through REST API . i have followed the document from this URL  https://docs.appdynamics.com/display/PRO45/Database+Visibility+API 

I was facing 500 internal server error with Exception ID : Exception Id:1b548637-3cb4-4dcf-86b4-ff4538d537b0 for both url's below.
