How to insert payload (number) into array in function node?

Third party integrations Node-RED

Hi,

I’m trying to pass a number to a function node (inside the array):

org%202019-05-04%2012-53-55
org%202019-05-04%2012-53-55994×560 225 KB

The final message I’m getting is “Hola. La temperatura es de [object Objetc] grados”, instead of “Hola. La temperatura es de 22 grados”.

What am I doing wrong? Thanks!

You’re overriding msg.payload on line 1 with an empty object then referencing that object on line 7 and 8.

const myArray = [
  `Hace ${msg.payload} grados`,
  `Hola. La temperatura es de ${msg.payload} grados`
];

const randomItem = myArray[Math.floor(Math.random()*myArray.length)];

msg.payload = { data: { message: randomItem } };

return msg;
