Enemy don not follow Player. Phaser3

Question

Can you please tell me where I made mistake in code ? why my enemy do not follow player? I am not sure if I defined correct followPlayer() . 'SceneB' is second Scene, can be this problem ? Console.log is clear . I am using EasyStar.js library. Game is working , everything is running but enemy is frozen .
Thank you

 class SceneB extends Phaser.Scene {
    constructor(){
      super('SceneB')
    }
   //..


create(){

finder = new EasyStar.js()
    let grid = []
    let tile 
    for(let y = 0; y < map.height; y++) {
         let col = []
      for(let x = 0; x < map.width; x++) {
         tile = map.getTileAt( x, y )
         col.push( tile.index)
      }
      grid.push(col)
    }

    finder.setGrid(grid)
  
    let tileset = map.tilesets[0]
    let properties = tileset.tileProperties
    let acceptableTiles = []

    for (let i = tileset.firsgid - 1;i < tiles.total;i++) {
       if(properties[i].collides == false ) {
         acceptableTiles.push ( i+1)
       }
    }

       finder.setAcceptableTiles( acceptableTiles) 

}


update(){}

followPlayer(player,evil) {
      

      let toX = this.player.x
      let toY = this.player.y

      let fromX = this.evil.x
      let fromY = this.evil.y

      finder.findPath(fromX, fromY, toX, toY, function(path) {
         console.log(path)
         this.moveCharacter(path)
       })

       finder.calculate()
    }


      moveCharacter(path){
        let mytimeline = this.scene.tweens.createTimeLine()    

        for(let i = 0;i < path.length - 1;i++) {
          let ex = path[i + 1].x
          let ey = path[e + 1].y

            mytimeline.add({
             targets: this.player,
            x:{value: ex * map.tileWidth, duration: 200},
            y:{value: ey * map.tileHeight, duration: 200}
          })
        }
        mytimeline.play()
      }

followPlayer is never getting called, so the logic will never actually trigger.

You'll want to call this somewhere in your code, depending upon how you've implemented your player logic.

You may also want to check inside finder.findPath that path !== null , and do something if it is, as that could also cause an issue.

finder.findPath(fromX, fromY, toX, toY, function(path) {
 console.log(path);
 if (path !== null) {
     this.moveCharacter(path);
 }
});
