[Solved] Node "must have a self pin connection"

Development Programming & Scripting

EDIT: I solved the issue.
Inside the error-reporting macro, I had a function which had no target specified (i.e., the class which it came from).
The message could be more specific, but generally, it was my fault.

============================

What kind of situation can cause it?

Inside the macro that throws the error, I’m getting an element from “ZmienneWyboru” array. That’s the only thing I could suspect for making trouble.

I can’t tell from the screenshot, can you upload one of the macro too?

I solved the issue. Input (the target) of a node inside the macro was accidentally left empty.
