Hi, Iim having issue and difficultied to debug it, it would be lovely to see the content on variable on flow. Since the "status" of a module is a dynamic variable.. I suppose it can be diplayed also that (if it is not long..)  
Any other alternative?  
Thank you

You can use a JSONate expression in the debug node, and display it in the node status(limit 32 chars).`$flowContext("flow_var.property")` or globalContext().

thanks, glad there is one 🙂 I've placed a dubug node near, choosen J expression and typed globalContext(Salotto)  
Then I connect the wire to the event output, but I have an error: "Invalid JSONata expression: globalContext(Salotto)"

Is Salotto the name of the global variable? If so, the try `$globalContext("Salotto")`

Note, the name is case sensitive

Thanks to all, works, I see it in debug window 🙂  
I did remember about the status node and I implemented it, I prefer, for example:  
node.status({fill:"green",shape:"dot",text:global.get(intensity)})
