Failed to dump Object


I tried to setup 2 pwm gpio pins (Pin 3 and 4) following the hoverboard and RC PWM documentation. I manage to get it sorta working, but the mapping i think was out of range for one of the joysticks so it wasn’t responding. I tried to change the mapping range and got the above image. This show for both gpio4 and gpio3 when i try to dump the object. Changing the max and min parameters don’t seem to change anything.
