orbital with projectile type ITEM cause error in console

this skill causes error in console [Legacy attachment omitted]

• orbital{bulletType=ITEM;material=SKELETON_SKULL;onTick=SkeletonShield-Tick;onHit=SkeletonShield-Hit;onEnd=SkeletonShield-End;points=60;interval=1;duration=200;r=0;oy=1.5;ox=1;oz=-0.7;hp=false;c=1}

the skill works normally but the error is spamming console

i found out that the problem is in " bulletType=ITEM;material=SKELETON_SKULL " and after deleting this part it doesnt show, but i dont have part of my skill...
