vpxd.log:

2023-08-30T09:40:16.366Z info vpxd[31986] [Originator@6876 sub=Default opID=807849b] [VpxLRO] -- ERROR lro-2341806 -- propertyCollector -- vmodl.query.PropertyCollector.retrievePropertiesEx: vmodl.fault.ManagedObjectNotFound:
--> Result:
--> (vmodl.fault.ManagedObjectNotFound) {
-->    faultCause = (vmodl.MethodFault) null,
-->    faultMessage = <unset>,
-->    obj = 'vim.ClusterComputeResource:'
-->    msg = ""
--> }

As you can see in the above vpxd.log, a ManagedObjectNotFound exception occurs. This is when a request refers to a managed object that no longer exists or has never existed.

To resolve this issue, reboot the vCenter server to clear any bad cache and vmodl.query.PropertyCollector will work properly.
