@aaltay are you happy for the file to be excluded?
The issue is if I leave the import in the try block, I get None exceptions
all over the place for the timestamp object. Or is this simply because the try
block for imports is triggered by a requirement to import the first module in
the block and I have them in the wrong order?

> msg = pubsub.types.pubsub_pb2.PubsubMessage()

> The protobuf definition is here:-
> https://cloud.google.com/pubsub/docs/reference/rpc/google.pubsub.v1#google.pubsub.v1.PubsubMessage
> and so it looks as if the message_id and publish_time are not being parsed as

> expanding to include these as attributes, or they would need adding to the
> dictionary for attributes. This would only need doing for the _from_proto_str
> as obviously they would not need to be populated when transmitting a message
> to PubSub.
> My python is not great, I'm assuming the latter option would need to look
> something like this?
> attributes = dict((key, msg.attributes[key]) for key in msg.attributes)
