General
1

may bee a simple question - i have a change node:

with the following JSON:

{
    "args": [
        21
    ]
}

now i have to set the "21" dynamicly e.g. with msg.payload. If i do so i get an error "Invalid Token".
Or can i do thse same with a function node?

Thanks for any help

Change the type of the field to "Expression" and replace the 21 with payload.
