speed = this?.params?.speed
In this case, Is it possible to create pull requests for fixed this one.

nextjs (v.12.2)
swiper (v.6.8.4)

Expected Behavior

Error shown up in some error. (We found from monitoring tool)

@nolimits4web Hi, do you need more information ?

[zainali225]

Did you try to pass second argument of speed.In my case, it solved the issue
textSwiper.slideTo(imageSwiper.activeIndex, 0);

[chonlatit-tpit]

Hi, we didn't use .slideTo method but we use autoplay options.
The error occur when we use autoplay options then we change page and swiper try to slideNext (from autoplay option).

Our website use Next.js and we change with next router (change page without refresh)
