Cannot use VmomiSupport.VmomiJSONEncoder on ComputeResource or ClusterComputeResource.

Trying to use the VmomiJSONEncoder on ComputeResource or ClusterComputeResource objects. I have tried it two different ways but keep getting an InvalidProperty error from pyvmomi. Could you please point me in the right direction?

import atexit
import json

from pyVmomi import vim, VmomiSupport
from pyVim.connect import SmartConnectNoSSL, Disconnect

host = 'somehost'
user = 'someuser'
password = 'somepassword'
port = 443

v_session = SmartConnectNoSSL(host=host,user=user,pwd=password,port=port)
atexit.register(Disconnect, v_session)

content = v_session.RetrieveContent()

#1st WAY
container = content.rootFolder
viewType = [vim.ComputeResource] #this also does not work with vim.ClusterComputeResource
recursive = True

container_view = content.viewManager.CreateContainerView(container, viewType, recursive)
clusters = container_view.view

for cluster in clusters:
    #print(cluster)
    cluster_template = VmomiSupport.templateOf('ComputeResource')(cluster._moId, v_session._stub)
    obj_json = json.dumps(cluster_template, cls=VmomiSupport.VmomiJSONEncoder)
    print(obj_json)

container_view.Destroy()


#2ND WAY, this also does not work.
'''
children = content.rootFolder.childEntity
data = {}
for child in children:  # Iterate though DataCenters
    dc = child
    data[dc.name] = {}  # Add data Centers to data dict
    clusters = dc.hostFolder.childEntity
    for cluster in clusters:  # Iterate through the clusters 
        #print(cluster)
        #print(vars(cluster))
        #cluster_template = VmomiSupport.templateOf('ClusterComputeResource')(cluster._moId, v_session._stub)
        cluster_template = VmomiSupport.templateOf('ComputeResource')(cluster._moId, v_session._stub)
        obj_json = json.dumps(cluster_template, cls=VmomiSupport.VmomiJSONEncoder)
        print(obj_json)
'''

Thanks

Start with the supplied reproducer and read VmomiSupport.VmomiJSONEncoder, templateOf, and the ComputeResource or ClusterComputeResource property access involved in the lifecycleManaged InvalidProperty error. Trace why encoding requests that property, then verify that serializing these objects completes without the reported exception.
