@benoitadam  
I have one more, if I use 'setTimeout,' I get an error and node-red restarts.

```auto
let invar = msg.payload
node.warn('1 ' + invar)

let MyTimeOutID = context.get('MyTimeOutID') ?? undefined
node.warn(MyTimeOutID)

const timeout = 2 //60 * 10 // sec

function MyTimeOut() { 
if (MyTimeOutID != undefined) { clearTimeout(MyTimeOutID) } 
MyTimeOutID = setTimeout(function () { 
node.warn('2 ' + MyTimeOutID) 
//clearTimeout(MyTimeOutID) 
msg.payload = invar 
node.send(msg) 
context.set('auto', true) 
}, 1000 * timeout)
}

MyTimeOut()

context.set('MyTimeOutID', MyTimeOutID)

```

```auto

```

The same applies to 'setInterval'.

These may not be implemented yet?

Hi,

I just fixed the issue in version 1.2.6.

Here's a screenshot of my test.

It hadn't been added to Manage Palette yet, so I downloaded it via npm.  
All good now.
