Problem with Traccar 5.7 notifications
Notifications are sent directly when the data is received and processed.
If WhatsApp API returns exception for non existent user or something like that, Traccar may not handle the response correctly.
Try to call WhatsApp API with external tool, Postman, Curl, etc. for nonexistent number.
If the phone number is authorized, here is the answer

If the phone number is not authorized, answer timeout

It's look like the API reject request with non standard HTTP Status code.
1028 - A user_identity_changed system notification requires acknowledgementYou sent a message to a WhatsApp user who has potentially changed, and a user_identity_changed system notification was sent to you and is pending acknowledgement.Thanks for the answers, I will investigate what you tell me, from what I see it could be that the API blocks Traccar.
Context: I have Traccar 5.7 and I use an API to receive notifications by WhatsApp, as a requirement for the API to work, the phone number must be registered on the API side. Everything works correctly.
Problem: if a client modifies his phone number for another one and this number is not registered in the WhatsApp API, when sending the notification Traccar stops working, the location of the device is not updated and the other devices go to unknown status.
the error is recorded in the log.
If I delete the notifications assigned to the user, everything starts working again without any problem.
How do the notifications work when they are sent, are they queued?
So far I know "how" the error occurs but I don't know "why".
