HELP! I can't set Additional properties when deploy ova using pyvmomi.

networkObj = None
try:
content = si.RetrieveContent()
view = content.viewManager.CreateContainerView(content.rootFolder, [vim.HostSystem], True)
hostObj = [v for v in view.view]
view.Destroy()
for network in hostObj[0].network:
if network.name == networkName:
networkObj = network
except Exception as e:
log.error(e)
raise

networkMapping = vim.OvfManager.NetworkMapping(name=networkName, network=networkObj)
propertyMappingList = []

if propertyMappingDict:
    **for key in propertyMappingDict:
        propertyMappingList.append(vim.KeyValue(key=key, value=propertyMappingDict[key]))**

try:
    cisp = vim.OvfManager.CreateImportSpecParams(entityName=vmName, diskProvisioning=diskProvisioning,
                                                 networkMapping=[networkMapping], propertyMapping=propertyMappingList)
except Exception as e:
    log.error(e)
    raise

cisr = ovfManager.CreateImportSpec(ovf_handle.get_descriptor(), rp, ds, cisp)

if len(cisr.error):
    log.error("The following errors will prevent import of this OVA:")
    for error in cisr.error:
        log.error("%s" % error)
    raise Exception("cisr error.")

ovf_handle.set_spec(cisr)

lease = rp.ImportVApp(cisr.importSpec, dc.vmFolder)
while lease.state == vim.HttpNfcLease.State.initializing:
    log.info("Waiting for lease to be ready...")
    time.sleep(1)

if lease.state == vim.HttpNfcLease.State.error:
    log.info("Lease error: %s" % lease.error)
    raise Exception("Lease error: %s" % lease.error)
if lease.state == vim.HttpNfcLease.State.done:
    return 0

log.info("Starting deploy...")
try:
    ovf_handle.upload_disks(lease, host)
except Exception:
    raise
return 0

I refer the document esxi6.7 , I find propertyMapping is KeyValue[], then I fill the ovfkey into the list.
But it not work.
Can somebody help me ?
Thanks a lot.

Start at the CreateImportSpecParams call and the propertyMapping list shown in the issue, then inspect the OVF descriptor's property keys and the ImportSpec errors. Done means the additional properties are accepted during OVA deployment and their resulting values can be verified.
