I am working on Node-Red, and for my project I also use turf.js, which can be installed on node-red as well (node-red-contrib-turf).

This is how the structure looks:

With functionOne having this code:

msg.topic = "point";
msg.payload = [[-75.343, 39.984]];
return msg;

And functionTwo:

pt = msg.payload
msg.topic = "buffer";
msg.payload = [pt, 5, {units: 'kilometers'}];

return msg;

So, the first function is used to produce a point of type Feature as stated in the docs and I am passing it to the second one where I save it in the variable pt and then when I execute the whole thing it does not happen anything.

Does someone know what my mistake is?
