Hello, I am trying to send msg.payload objects through TCP/UDP, but it seems it doesn't send msg.payload.XXXX properly. Is there a setting I am missing, or am I not supposed to send msg.payload.XXXX objects through TCP/UDP nodes.
If I am not supposed to what is a good way of sending list of messages though TCP/UDP nodes?
Try adding a json node after the udp-in node and see what you get

Thank you for your response.
Adding json node gave me this following error message.
"Unexpected token o in JSON at position 1"
You need to convert the object to a JSON string prior to the udp out node, so the json node needs to be there as well.
e.g.
