Do_Set_Servo Command Execution Error

Hello!
I have a problem with do_set_servo command in auto flight.
I got that error message above after do_set_servo WP passed.

I got two bay doors under the plane. I need to drop a tennis ball and then the door should be closed after the ball drops. The problem is that the doors open but doesn’t close.
