SOLVED: Need help with custom exploding bullets enchant

It looks like imediatesourceentity is missing since i see it under "When projectile hits block" but not to the bottom right in the actual procedure

This is the procedure:

if: Has Provided itemstack enchantment CUSTOM:ExplosiveBullets

do: Explode at x: x y: y z: z with power 2 type: BREAK

Update: Fixed it by changing from Has provided itemstack to has item in main-hand of event/ target entity
