Ion-slides with auto play in Ionic3

I am using ion-slides on my home page, but it is not working with autoplay.

Ionic code:

    <ion-slides autoplay=300>
      <ion-slide  *ngFor = "let banners of bannersImage">
        <img src={{banners.image}}>
      </ion-slide>
    </ion-slides>

Error message:

Uncaught TypeError: Cannot read property 'hasAttribute' of undefined
