Issue/Introduction

In Aria Operations UI, on the 'Manage Telegraf Agents' page you have a VM that has a constant spinning status of "Uninstall in Progress" which has been like this for a very long time.

If you manually click on Uninstall under 'Agent Actions' for this VM. the uninstall fails with blank error message in the UI.
