Code to make entities go through solid blocks

Im trying to add a custom code snippet to a flying mob to make it go through solid blocks like a Vex but it doesnt seem to work.

The code: 
@Override
public void travel(Vec3 movementInput) {
    if (this.isInWater()) {
    } else if (this.isInLava()) {
    } else {
        float friction = 0.91F;
        if (this.onGround) {
            friction = this.level.getBlockState(this.blockPosition().below()).getBlock().getFriction();
        }
        float groundFriction = 0.16277136F / (friction * friction * friction);
        this.moveRelative(this.onGround ? 0.1F * groundFriction : 0.02F, movementInput);
        friction = 0.91F;
        if (this.onGround) {
            friction = this.level.getBlockState(this.blockPosition().below()).getBlock().getFriction();
        }
        this.move(MoverType.SELF, this.getDeltaMovement().multiply((double) friction, 1.0D, (double) friction));
        this.setDeltaMovement(this.getDeltaMovement().scale(1.0D / (double) friction));
    }
}

The error i get:
