Rotate an image according to the Tween

[Bihos]

Hello, first of all forgive me for my English, it is very bad.
I'm trying to rotate an Sprite based on the Tween.
I add a tween for each point of the road as seen here:

  var tweens = [];
  for(var i = 1; i < path.length; i++){
      var ex = path[i].x;
      var ey = path[i].y;
      
      if (i == path.length-1)
      {
        tweens.push({
          targets: soldier,
          x: {value: ex*64+32, duration: 600},
          y: {value: ey*64+32, duration: 600},
          onComplete: onCompleteHandlerFinal
        });
      }

      else
      {
        tweens.push({
          targets: soldier,
          x: {value: ex*64+32, duration: 600},
          y: {value: ey*64+32, duration: 600},
          onComplete: onCompleteHandler,
          onStart: onStartHandler
        });
      }
      
  }
  scene.tweens.timeline({
    tweens: tweens
  });

 

and I have a function that rotates my object (Spirte), which receives the points x and y where it should point:

rotate (to_x, to_y, delta){
  let myPoint = new Phaser.Geom.Point(this.x+32,this.y+32);
  let pointTo = new Phaser.Geom.Point(to_x+32, to_y+32);
  this.rotation = Phaser.Math.Angle.BetweenPoints(myPoint, pointTo) + delta;
}

my idea is to rotate the image in the onStartHandler method, but I can not get the coordinates of the point where it is going.

function onStartHandler (tween, targets, gameObject)
{
  console.log(targets[0].x);
  console.log(tween.anyMethod()); //I need a method that returns the x coordinate
                                  //where the sprite goes in this tween
}
