Short description of error
Create any object, for ex cube (click add->mesh->cube). Add armature to the scene (click add->armature). Add armature modifier to the cube. In the modifier settings select created armature as deforming object. Then go to the sculpt mode, try to draw face set on the cube, notice it does not work.
