Diagnosing "vSphere object not known to vCD" error message

I have a vCenter/vCD lab setup at home and am getting the following error message when I try to create a simple vApp.  Can someone explain how I can diagnose the resource pool problem from this message.

   The vSphere object ResourcePool:resgroup-58 on com.vmware.vcloud.entity.vimserver:136c55e2-80bb-40f8-ab71-29b41f296b98 is unknown to VCD.

Thanks for the help.
