container getBounds getTransformMatrix is not a function

[poasher]

The following code causes an error :

         let cont0 = this.add.container(0, 0);
         let cont1 = this.add.container(0, 0);
         cont0.add(cont1);
         let backMask = new  Phaser.GameObjects.Graphics(this, null);
         backMask.fillStyle(0x000000);
         backMask.fillRect(0, 0, 500, 500);
         backMask.generateTexture('backMask1');
         let image = this.add.image(0 , 0 , 'backMask1');
         cont1.add(image);
         cont1.getBounds();
