The Javascript code inside **function nodes** cannot be debugged, but if you create your own **custom node** then you can debug it (like you can debug all other Node-RED nodes). I have explained [here](https://discourse.nodered.org/t/how-to-debug-an-own-node-with-the-node-js-debugger/5737/4) how you can debug Node-RED using a Chrome debugger, in case you ever need it...
