Bulk Removal of System.Categories Value

Going to drop an update that this script ran great for devices not in the cloud.  The calls to update our 100+ devices in Azure returned a 200 OK without changing the content of the system.categories field.

I did try different find-replace or escape functions or even changing to v3 with no improvement yet.  The Swagger for v3 API also talks about system.categories being an exception.

    <# Request Info #>
    $httpVerb = 'PATCH'
    #$resourcePath = '/device/devices/' + $item.id #v1 query
    #$queryParams = '?patchFields=customProperties&opType=replace' # v1 query
    $resourcePath = '/device/devices/' + $item.id + '/properties/system.categories' #v3 query
    $queryParams = '?v=3' # v3 query

    #$data = '{"customProperties":[{"name":"system.categories","value":"' + $item.NewData + '"}]}' # v1 data payload
    $data = '{"value":"' + $item.newData + '"}'  # v3 data payload

    # v3 data mangling
    #$value = [uri]::EscapeDataString($item.NewData)
    #$value = $item.newData.replace('/','%2F')
    #$value = $item.newData.replace('/','%252F')

    #$data = '{"customProperties":[{"name":"system.categories","value":"' + $value + '"}]}' # v1 data payload
    #$data = '{"value":"' + $value + '"}' # v3 data payload

The audit log in LogicMonitor has records of my calls but the middle is blank.  I did update my case with LogicMonitor Support - this is an interesting one.
