This happens when the vmFolder of vCenter's datacenter doesn't have any child folders. Workaround is to create some temporary folder under vmFolder using vSphere client.

    VMware:Fix error creating vCenter inventory folder

    Creating vCenter inventory folder for grouping volumes will
    fail with AttributeError if the vCenter's datacenter doesn't
    have any child folder under vmFolder (inventory folder for
    grouping virtual machines). This patch fixes it.
