[BUG] PowerCLI New-TagAssignment is not sending an event

[cabarria]

Describe the bug
When using PowerCLI to tag a VM no event is registered.

To Reproduce
Run the following PowerCLI script (update values as needed)

$vmName = "VMName"
$categoryName = "Category"
$tagValue = "TagValue"
$clusterName = "ClusterName"
$vCenter_FQDN = "vCenter IP or DNS Name"
$credential = Get-Credential -Message "Enter your vCenter credentials"
Connect-VIServer -Server $vCenter_FQDN -Credential $credential
$cluster = Get-Cluster -Name $clusterName
$vm = Get-VM -Name $vmName -Location $cluster
$category = Get-TagCategory -Name $categoryName
$tag = Get-Tag -Name $tagValue -Category $category
New-TagAssignment -Tag $tag -Entity $vm

Here is the output from running the script:
Name Port User
vcenter_server 443 domain.com\UserName

Uid : /VIServer=domain.com\UserName@vcenter_server:443/VirtualMachine=VirtualMachine-vm-2111/TagAssignment=/Tag=urn:vmomi:InventoryServiceTag:b74
7ab6f-c49c-4593-9578-8ab5e3c96e2f:GLOBAL/
Tag : category_name/tag_value
Entity : vmautotag-99
Id : com.vmware.cis.tagging.TagAssociationModel
Name : com.vmware.cis.tagging.TagAssociationModel

Expected behavior
The following event should have been generated:

{
"Key": 109354,
"ChainId": 109354,
"CreatedTime": "2023-07-18T19:06:56.401Z",
"UserName": "domain.com\UserName",
"Datacenter": null,
"ComputeResource": null,
"Host": null,
"Vm": null,
"Ds": null,
"Net": null,
"Dvs": null,
"FullFormattedMessage": "User domain.co\UserName attached tag tag_value to object vmautotag-99",
"ChangeTag": "",
"EventTypeId": "com.vmware.cis.tagging.attach",
"Severity": "info",
"Message": "",
"Arguments": [
{
"Key": "Tag",
"Value": "tag_value"
},
{
"Key": "Object",
"Value": "vmautotag-99"
},
{
"Key": "User",
"Value": "domain.com\UserName"
}
],
"ObjectId": "",
"ObjectType": "",
"ObjectName": "",
"Fault": null
}

Version (please complete the following information):

• VEBA Form Factor: Appliance
• VEBA Version: v0.7.5
• vCenter Versions: 7.0.3.01400 and 7.0.3.00500

Additional context
Adding/Removing tags through the UI works as expected.

Unfortunately, I believe this is a limitation in vSphere Tagging when it is triggered through PowerCLI which might be using a different backend API than the one used by vSphere. Since the vCenter Event isn't being generated, VEBA won't receive any event.

I would recommend filing an SR w/VMware Support to identify the API, so that you could initiate via PowerCLI to get the same behavior as vSphere UI, but this isn't a defect with VEBA itself as vCenter Server itself isn't producing the event in the first place

In case someone else runs into the same issue, here is the workaround:

    $category = Get-TagCategory -Name $categoryName
    $vm = Get-VM -Name $vmName
    $tag = Get-Tag -Name $tagValue -Category $category
    $vminfo = $vm.ExtensionData.MoRef
    $vmid = Initialize-StdDynamicID -Type $vminfo.Type -Id $vminfo.value
    $tagAssociation = Initialize-TaggingTagAssociationAttachRequestBody -ObjectId $vmid
    Invoke-AttachTagIdTagAssociation -TagId $tag.Id -TaggingTagAssociationAttachRequestBody $tagAssociation
