我遇到以下错误：

  

无法读取未定义的属性“ width”   在新的Phaser中。瓷砖图

我的脚本：

var game = new Phaser.Game(1024, 640, Phaser.AUTO, 'auto-def', { preload: preload, create: create, update: update });

let map;

function preload () {
    game.load.tilemap('td-map-1", "./assets/auto-def-1.json',null, Phaser.Tilemap.TILED_JSON);
    game.load.image('tiles','./assets/tilesheet.png');
}

function create () {
  map = game.add.tilemap('td-map-1');
  map.addTilesetImage('tilesheet', 'tiles');
  layer = map.createLayer('yer');
  layer.resizeWorld();
}

function update () {
}

上面引用的“ auto-def-1.json”文件的内容：
