DeliveredMessage.reply_to doesn't exist

[matthewtrotter]

In an RPC framework, the server cannot access the reply_to variable of the message. It doesn't seem to exist, or I can't find it.

Server code:

# Setup/connect
await self.chan.queue_declare(self.requests_queue)
await self.chan.basic_consume(self.requests_queue, self._process_request)

async def _process_request(self, request):
    # Do stuff

    # Respond
    await request.channel.basic_publish(
        body=response_bin, 
        routing_key=request.reply_to,
        properties=aiormq.spec.Basic.Properties(
            correlation_id=request.correlation_id
        )
    )

Error:

AttributeError: 'DeliveredMessage' object has no attribute 'reply_to'
