Issue in arduino pins procedure.

I´m trying to make the simplest thing with Mcreator and Arduino, turn on a led. I do everything like every tutorial I find says and when I compile the procedure that sets if the pins will be inputs or outputs, it cause a problem that I can´t find a solution yet. It dosen´t compile. I´ve tried using a new workspace but it didn´t work. I´m using Mcreator 2021.3
