The node object is exposed in the context of a function node and had 2 functions that will add something to the debug tab

node.warn() and node.error() both print to the debug tab (and also to the console) but with suitable colours and header messages e.g.

node.warn(msg.payload);
return msg;

warn and error messages in debug tab

Be aware that node.error will also raise a message that can be caught by the Catch node so if you just want to report status from with in a function then the node.warn is probably best
