Hi i keep getting an error in my " create filename node"
Here is my workflow

Here is the error after trying the event.

Any idea how i can resolve this?

Thanks

The error message shows :

$input.item.json.sender is undefined. So it can not be split.

The screenshot can not tell where is the sender. Can you give another screenshot?

If you want to get the sender like this screenshot

You can use the code

let sender = $input.first().json.from.value[0].name
