Remove tags from a virtual machine

[BoHu1977]

How can I remove 1 or more tag(s) from a virtual machine? I use the API virtualization \ virtual machine with code for the action.

Part of the code:
$TAGS["tags"] = $null
$UpdateNetBoxVM ConvertTo-JSON $TAGS
$URI = $URIBase + "/virtualization/virtual-machines" + "//"
$Respons = Invoke-RESTmethod -Method PATCH -Headers $Headers -ContentType "application/json" -Body $UpdateNetBoxVM -URI $URI

Please show your existing code and what you've tried. Presuming you are talking about the REST API, are you using pynetbox or requests or curl or some other client library?

I think that code has been mangled by markdown rendering. Please can you edit the post and put three backticks (```) on a line of their own, before and after the code.

I'm not sure what language it is: PowerShell perhaps?

I think you need to set the tags to the empty list - [] - instead of Null.

If you can show the JSON contents of the request body being sent, which I think is whatever is stored in $UpdateNetBoxVM, that would make it clearer.

The language is indeed PowerShell.
I Tried the [], but it fails. The error code Invoke-RESTMethod: {"details:""Not found"} is show
The content of UpdateNetBoxVM is a System.Collections.DictonaryEntry with the content of
{
"tags": null
}

And can you show the content of UpdateNetBoxM when you set tags to empty list?

Also, please can you edit your first post to add the three-backticks lines for quoting your code block.

Right now I see $URI = $URIBase + "/virtualization/virtual-machines" + "//" and that can't be right.

Tested with curl it works fine (Netbox 3.3.7), so it must be that your PowerShell fu is the problem.

# curl -gsS -H "Authorization: Token $API_TOKEN" "https://$NETBOX/api/virtualization/virtual-machines/8/" | jq '.tags'
[]

# curl -d '{"tags":[9]}' -X PATCH -gsS -H "Content-Type: application/json" -H "Authorization: Token $API_TOKEN" "https://$NETBOX/api/virtualization/virtual-machines/8/"
... snip response ...

# curl -gsS -H "Authorization: Token $API_TOKEN" "https://$NETBOX/api/virtualization/virtual-machines/8/" | jq '.tags'
[
