[1.18.1] Why entity not go to specific position

[grossik]

Hi

I try to get custom entity to a specific position which is located above the diamond block, but the entity stops next to the block and doesn't continue. Where is the problem? How can I get my entity to position above the diamond block?

Custom goal:

public class TestMoveToPositionGoal extends Goal {

	protected MiniGolemEntity mob;
	protected BlockPos blockPos;
	protected int index;
	protected int tryTicks;

	public TestMoveToPositionGoal(MiniGolemEntity entity, int index) {
		this.mob = entity;
		this.index = index;
		
		this.setFlags(EnumSet.of(Goal.Flag.MOVE, Goal.Flag.JUMP));
		
		blockPos = new BlockPos(8, -60, -19);
	}
	
	@Override
	public void tick() {
		super.tick();
		
		if(!blockPos.closerThan(this.mob.position(), 1D)) {
			this.tryTicks++;
			if(this.shouldRecalculatePath()) {
				System.out.println("recalculate");
				mob.getNavigation().moveTo(blockPos.getX() + 0.5D, blockPos.getY(), blockPos.getZ() + 0.5D, 1F);
			}
		} else {
			this.tryTicks--;
			mob.getNavigation().stop();
			mob.chanceStatus(index);
			System.out.println("finish");
		}
	}
	
	@Override
	public void start() {
		super.start();
		tryTicks = 0;
	}
	
	public boolean shouldRecalculatePath() {
		return this.tryTicks % 40 == 0;
	}	
   
	@Override
	public boolean canUse() {
		return mob.canUseGoal(index);
	}
}

Entity only recalculate path, but doesn't move. I know. I can solve it by increasing the radius, but I don't want to.
