I set swiper.js to navigate through different questions using ReactJS. I'm trying to change the {quesNumber} state with swiper's onSlideChange method, which should set the "q" URL parameter based on the current question's number ("q-{quesNumber}"). I've managed to so, but it is stuck on the first slide and not changes to the next one. I'm receiving this error on the console:
Uncaught TypeError: Cannot read property 'removeClass' of undefined

- Here is my code:
import React, { useContext } from "react";
import { useHistory } from "react-router-dom";
// Import Swiper React components
import SwiperCore, { Navigation, Pagination, A11y } from "swiper";
import { Swiper, SwiperSlide } from "swiper/react";
import { Context } from "../Context";
// Import Swiper styles
import "swiper/swiper.scss";
import "swiper/components/navigation/navigation.scss";
import "swiper/components/pagination/pagination.scss";
import "swiper/components/scrollbar/scrollbar.scss";
function Carousel() {
let { quesNumber, setQuestNumber } = useContext(Context);
let history = useHistory();
function nextQuestion() {
setQuestNumber(quesNumber + 1);
history.push(`/q-${quesNumber + 1}`);
}
SwiperCore.use([Navigation, Pagination, A11y]);
return (
<Swiper
loop={false}
slidesPerView={"auto"}
navigation
spaceBetween={0}
freeMode={true}
pagination={{ clickable: false }}
// onSwiper={() => (setQuestNumber(quesNumber ++))}
onSlideChange={() => nextQuestion()}
// onClick={() => console.log(nextQuestion())}
>
<SwiperSlide>slide 1</SwiperSlide>
<SwiperSlide>slide 2</SwiperSlide>
<SwiperSlide>slide 3</SwiperSlide>
<SwiperSlide>slide 4</SwiperSlide>
</Swiper>
);
}
export default Carousel;
import React, { useContext } from "react";
import { useHistory } from "react-router-dom";

let history = useHistory();
function nextQuestion() {
setQuestNumber(quesNumber + 1);
history.push(`/q-${quesNumber + 1}`);
}
SwiperCore.use([Navigation, Pagination, A11y]);
return (

Thanks :)
