Getting a error, when i try to collect Data from vCenter Server. But Cluster Collection works !?

Hello,

I´m getting a strange errormessage when it try to load the Inventory from my vCenter Server.

I configured my vCenter Server as Endpoint and i was able to load the Clusters. When i klick Data Colection from a Cluster (EQL Cluster 1) i can load all Data and the status is "Succeeded" but when i try to load the inventory fro the vCenter Server (to get the Templates) im getting this error message:

Error processing [inventory], error details: Illegal managed object reference type, Folder.

The Agent-Logs schows the same:
