Hello Team,
I'm using docker image of tomcat to deploy an spring boot app and configured the java agent as per instructions.
All though I see the following message
[AD Agent init] 02 Nov 2023 13:30:10,183 INFO JavaAgent - Started AppDynamics Java Agent Successfully.
Right after that I see the following error. I replaced the first part of saas controller name to test to sanitise the original url. There's no proxy in my case. Not sure what is happening
