Hi Devs, When working with the single cartridge application I too faced the same issue when trying to undeploy the auto-scaling policy and application. However, in my case as I modified the sample and made it a multi-tenant application and deployed it I was not sure whether it was something that I did wrong that triggered this to happen. Therefore, I did not report the issue. However, if Shavindri has faced a similar issue I think that it is worth looking into.
