What is the error?

You are passing an empty array topeyelid to segmentiris

It appears that you are relying upon handles.output to be non-empty while you are still inside your GUI. handles.output is not normally set to non-empty until the GUI is shutting down. That is not a hard rule, but it is unusual enough to be worth investigating.
