Dashboard 2.0 Notification - Dual Output Messages

[Skaedian]

Hi there

I'm working in Node-RED 4.0.5 with a notification node and noticed that this node outputs two messages:

The notification node is configured like this:

Is it normal for the notification node to output two messages?

(Here is a copy of the flow)

In my other flow I used the notification node in line with the flow and noticed that all actions are duplicated. In my other flow, the notification node is placed like this:

I can re-wire the flow like this and my problem will be solved:

I just need to know if the two messages that the notification node outputs is a bug or not. I might be missing something.

Thank you.

No, it's not a bug; it's normal behavior. The first message printed in the output occurs when you click the inject button or trigger the notification widget to show the notification. The second message is printed when the duration you have defined in the notification widget ends. You can see the second message with the payload: 'timeout.' It will also generate the message when you interact with the notification, such as by clicking the close button.

Thank you @sumitshinde-84 for the confirmation. Much appreciated. I will re-order my flow to take this into account.
