Would an object launched by the Catapult spell do full damage against a Scarecrow?

A Wizard uses the spell Catapult (EEPC, p. 15-16; XGtE, p. 150) against a Scarecrow (MM, pg. 268).

Catapult flings an object that is not worn or carried toward a scarecrow and hits.

The scarecrow has damage resistance to bludgeoning, piercing, and slashing from nonmagical weapons.

Does Catapult do full damage, or reduced damage in this scenario?
