Sometime Object Message is Empty

[azickri]

Hello, Whatsmeow Team.

Does anyone often experience cases like ours? We get a Listener with Message data that has no contents or is empty. How do we handle this message?

It is looks like a custom message ID.

@JustSoursop So, it doesn't mean anything?

[SoursopID]

There is a possibility that the message sent is actually empty.

[azickri]

Do you mean, like empty text?

[SoursopID]

Just empty or nil. var msg = nil or var msg = proto.Message{}. Printing a debug log might help to see the actual XML proto message before it is parsed into a Go struct.
