Relating to an issue (#51668) , now resolved, regarding setting broker properties.

I am unable to set the 'Label' property in a service bus message.

Building on the code from from the previous feedback:

``
from azure.servicebus import ServiceBusClient, Message

CONNECTION_STR = ''
QUEUE_NAME = 'queue`'

Create SB client

sb_client = ServiceBusClient.from_connection_string(conn_str=CONNECTION_STR)

Create Queue sender

queue_sender = sb_client.get_queue(queue_name=QUEUE_NAME)

Build message

message = Message("{'data':'Hello World!'}")

Custom Properties

message.user_properties = {'Label': 'Shell.Energy.Europe.Power.Meter.Actual'}

Brokered Properties

message.properties.content_type = "application/json"
message.properties.label = "M4"

Send message

queue_sender.send(message)
``

The result is that the ContentType is set as "application/json", however the Label property remains empty. I am able to set other properties such as 'ReplyTo' so Am not sure why the Label can't be set this way too?

Any help is much appreciated, thanks

I figured it out! instead of properties.label, it should be properties.subject
