Receiving "Failed to uninventory the selected resources" message trying to un-inventory platform in JBoss ON

Issue

• I have been trying to uninventory a few platforms that we have decommissioned. Unfortunately when I click the "uninventory" button, I get an error message "Failed to uninventory the selected resources"
• Attempt to remove platform from inventory fails with the following messages:
