Description

Hello,

Have you guys seen this error when applying a license?

File "/usr/lib/python2.7/site-packages/pyVmomi/VmomiSupport.py", line 580, in 
self.f(*(self.args + (obj,) + args), **kwargs)
File "/usr/lib/python2.7/site-packages/pyVmomi/VmomiSupport.py", line 386, in _InvokeMethod
return self._stub.InvokeMethod(self, info, args)
File "/usr/lib/python2.7/site-packages/pyVmomi/SoapAdapter.py", line 1366, in InvokeMethod
raise obj # pylint: disable-msg=E0702
vmodl.fault.InvalidArgument: (vmodl.fault.InvalidArgument) {
dynamicType = ,
dynamicProperty = (vmodl.DynamicProperty) [],
msg = 'A specified parameter was not correct: entityId',
faultCause = ,
faultMessage = (vmodl.LocalizableMessage) [],
invalidProperty = u'entityId'
}

This is the code that calls the application of the license:

ic_mgr = content.licenseManager
    lic_mgr.AddLicense(lic_key)
    if description:
        lic_mgr.licenseAssignmentManager.UpdateAssignedLicense(
            entity_id, lic_key, description)
    else:
        lic_mgr.licenseAssignmentManager.UpdateAssignedLicense(entity_id, lic_key)

We are getting an error with the entity_id variable even though we assign that variable with a hard-coded value when applying a NSX license. Retrying solves this issue, however, I want to know if you guys are aware of this or know a little bit more about this issue? Any ideas on how to stop getting this issue?

Research direction
The issue involves an intermittent error when assigning a license via pyVmomi's UpdateAssignedLicense method, with the error indicating an invalid entityId. The root cause is unclear but may be due to transient state or race conditions in the VMware API. Investigate the pyVmomi SOAP invocation (VmomiSupport.py, SoapAdapter.py) to understand how entityId is passed and whether retries are safe. Also check if the issue is reproducible in different environments and if there are any known workarounds in the community.
