I have a inject node injecting a string into a function node - The function node sets a flow.set to the string -- Happy days.
All of a sudden with no changes this flow now set the flow.set to "[object Object]" -- Un happy days.
Copy the nodes and past it in the same flow - the one set the flow.set to the string the other to "[object Object]" --- And yet the one is a copy of the other. -- The only reasons I copied the node were to try and establish what went wrong.

I changed the flow.set("dbc.xxx) and now it works - stores the correct value

Looks like you got it sorted - somewhere, an object started moving through your flow where you were expecting a string.
