It’s a technical coding error. In the codebase “null” should actually be your actual first name. But there’s a bug in the codebase where your name, for whatever reason is not displaying. So the code will default to “null” or “undefined” depending on how the code is written. So the code could probably look something like this. const name = “John”; If (name) { return ‘${name} unsent a message’; } But if your name is missing, const could like like tbis: const name = null; null literally means nothing in the coding word. And it’s like an empty placeholder. Answer from pigeonJS on reddit.com

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?

That happens if you have multiple devices logged on in the same account. For example in Device A, you've received a message from a person or group chat but you archived it. Then when you open Device B, you will receive the message again but now it will show "null", cause it cant show the message anymore as you archived it or hide it in Device A. That is based on my experience as I always hid messages on my Messenger app. Assuming that you dont know that girl or person, maybe they deleted the chat immediately (you can still delete a message if it was not yet delivered). Or the person had their account deactivated.

r/NoStupidQuestions on Reddit: Why do I keep getting "null sent a message" on Facebook messenger every 20 minutes
December 3, 2022 -
I keep getting a Facebook Messenger notification on my phone every 20 minutes that says " null sent a message "
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

February 11, 2025 - The following scenarios can lead to a message being represented as null within Facebook Messenger: Explicit User Deletion: When a user consciously deletes a message using the ‘Remove for Everyone’ or ‘Unsend’ feature, the underlying database entry containing the message content is often either completely removed or its content field is set to null. This ensures that the message is purged from both the sender’s and recipient’s view. Depending on Facebook’s implementation, the metadata related to the message (timestamp, sender ID, etc.) might still be retained for auditing or operational purposes, but the actual message body is nulled.

devRant - I keep getting contacted on Facebook Messenger by "null", and receiving "message" from my friends. How can a social network suck so much? And how can a company spend so much money on declarative programmers without the rest of their teams picking up on such basic techniques as making invalid state unrepresentable?
Just because null exists in your language doesn't mean you have to assign it to anything. ... @ostream It's really not though, it's the programmer's choice to assign the placeholder string "message" instead of unfucking the construction order so that the message body only needs to be specified when it's available.
