Why do I keep getting "null sent a message" on Facebook messenger every 20 minutes
(null) is calling on messenger keeps popp… - Apple Community
I received a notification on messenger saying "null sent a message.". Next to that notification, there's a girl's profile picture. I checked my messenger including the spam folder and "message requests", but there's nothing in there. If I open the notification, will it display the girl's name?
What does it mean when someone texts 'null'?
Why is 'null' showing up in my messages?
How should I respond when I see 'null' in a message?

You could also check on http://www.google.com/contacts and check if the address book entry for that person is missing some information.

Google does not have any results. Even when I throw quotes around the search, Google still is not providing anything relevant. All Google shows when searching with quotes is YouTube to MP3 results and NONE actually include "null sent a message"
Checking my messages, there are no messages but I am getting this every 20 minutes
What does this mean?
This is the notification that I've received. I would really like to know who the girl is, but I'm afraid of opening the notification in case this is a virus? Will opening the notification show me this girl's name?
I unsent a message for everyone, the message is deleted but the message is "null unsent a message"
In MVVM Light V4 beta, a regression bug was introduced that causes null messages to fail with a NullReferenceException. This bug will be fixed ASAP.

I'm not familiar with the particular library in question, but if you're calling a method with a generic parameter, you cannot simply pass null because null means "nothing" and it needs a particular kind of nothing. So for a method like void Send<TMessage>(TMessage messgae), you would have to do something like:
Send<string>(null);
or
Send((string)null);
If you subsequently get runtime exceptions (e.g. NullArgumentException), then you could think about defining a NoMessage type with some kind of default/nothing behavior that you want to encapsulate (see Null Object Pattern).
