I'm having a weird problem. A bit of background first: I have a configuration node that gathers information of the current flow's nodes and calls some external APIs, after which another fresh flow is created with the additional information from these APIs.
Now, when I install this node, in all flows that I have open, none of the sidebar nodes can be drag-dropped. I mean they are perfectly draggable, but once I drop them they do not remain on the canvas. It's as if the canvas has suddenly become read-only.
I've already checked: uninstalling this node solves this problem. Does anyone have a clue as to what could trigger such behaviour? I'm unfortunately not able to share the code here because it's still proprietary.
