Additional context

In my NextJS 14 app, I am trying to get a Swiper working.
My issue is that only the first slide works, the other ones are not visible. When I console.log my slide images to ensure they are loaded correctly, I can see that they are so the issue isn't there. If I put the same image for all the slides, only the first one loads still. So the issue isn't from the images I am trying to use in my swiper. I also tried several other packages offering carousels/swipers, and even written by myself without a package, all the codes I have tried led to the same issue, one slide only. I figured at some point that it looks like the 3 images/ slides are actually appearing yet the last two for just a second, then they vanish, leaving only the first one on screen. It really seems to be the case with every swipers. I also tried "use client", without success...

You can check the issue on this page, it's the carousel swiper on this same page: https://wave-riders-ecommerce.vercel.app/

Please note that the first slide is also controllable with the mouse while the other 2 aren't. Which means they probably just aren't there, while the pagination shows my three items properly...
Here is my code:

"use client";
import React, { useRef, useState } from "react";
import { Swiper, SwiperSlide } from "swiper/react";
import "swiper/scss";
import "swiper/scss/pagination";
import { Autoplay, Pagination } from "swiper/modules";
import Image from "next/image";
import slide1 from "../../public/assets/img/surfboard.jpg";
import slide2 from "../../public/assets/img/beach-surfers.jpg";
import slide3 from "../../public/assets/img/homepage-bg.jpg";
import "./Carousel.scss";

export const Carousel: React.FC = () => {
  const images = [slide1, slide2, slide3];

  console.log("slide 1: ", slide1); // output: slide 1:  Object{...}
  console.log("slide 2: ", slide2); // output: slide 2:  Object{...}
  console.log("slide 3: ", slide3); // output: slide 3:  Object{...}

  return (
    <>
      <Swiper
        pagination={{ clickable: true }}
        modules={[Pagination, Autoplay]}
        autoplay={{
          delay: 3000,
        }}
        className="swiper"
      >
        {images.map((imageUrl, index) => (
          <SwiperSlide key={index} className="swiper__slide">
            <div className="swiper__slide__img-container">
              <Image
                src={imageUrl}
                alt="image"
                layout="fill"
                objectFit="cover"
                className="swiper__slide__img-container__img"
              />
            </div>
          </SwiperSlide>
        ))}
        <div></div>
      </Swiper>
    </>
  );
};

I have tried downgrading my swiper version as I used it in a recent NextJS project in which I had no issue, but no luck either. I also tried downgrading my NextJS version, nothing either.
Here is what my current package.json looks like, in case it may help...

{
  "dependencies": {
    "@reduxjs/toolkit": "^2.2.3",
    "@supabase/supabase-js": "^2.43.1",
    "dotenv": "^16.4.5",
    "next": "14.2.3",
    "react": "^18",
    "react-bootstrap": "^2.10.2",
    "react-dom": "^18",
    "react-icons": "^5.2.1",
    "sass": "^1.77.0",
    "swiper": "^11.0.5"
  },
  "devDependencies": {
    "@types/node": "^20",
    "@types/react": "^18",
    "@types/react-dom": "^18",
    "eslint": "^8",
    "eslint-config-next": "14.2.3",
    "typescript": "^5"
  }
}

Hope someone can help! Thanks :)

[github-actions]

We could not detect a valid reproduction link. Make sure to follow the bug report template carefully.

Why was this issue closed?

To be able to investigate, we need access to a reproduction to identify what triggered the issue. We need a link to a public GitHub repository (template for App Router, template for Pages Router), but you can also use these templates: CodeSandbox: App Router or CodeSandbox: Pages Router.

The bug template that you filled out has a section called "Link to the code that reproduces this issue", which is where you should provide the link to the reproduction.

• If you did not provide a link or the link you provided is not valid, we will close the issue.
• If you provide a link to a private repository, we will close the issue.
• If you provide a link to a repository but not in the correct section, we will close the issue.

What should I do?

Depending on the reason the issue was closed, you can do the following:

• If you did not provide a link, please open a new issue with a link to a reproduction.
• If you provided a link to a private repository, please open a new issue with a link to a public repository.
• If you provided a link to a repository but not in the correct section, please open a new issue with a link to a reproduction in the correct section.

In general, assume that we should not go through a lengthy onboarding process at your company code only to be able to verify an issue.

My repository is private and cannot make it public

In most cases, a private repo will not be a sufficient minimal reproduction, as this codebase might contain a lot of unrelated parts that would make our investigation take longer. Please do not make it public. Instead, create a new repository using the templates above, adding the relevant code to reproduce the issue. Common things to look out for:

• Remove any code that is not related to the issue. (pages, API routes, components, etc.)
• Remove any dependencies that are not related to the issue.
• Remove any third-party service that would require us to sign up for an account to reproduce the issue.
• Remove any environment variables that are not related to the issue.
• Remove private packages that we do not have access to.
• If the issue is not related to a monorepo specifically, try to reproduce the issue without a complex monorepo setup

I did not open this issue, but it is relevant to me, what can I do to help?

Anyone experiencing the same issue is welcome to provide a minimal reproduction following the above steps by opening a new issue.

I think my reproduction is good enough, why aren't you looking into it quickly?

We look into every Next.js issue and constantly monitor open issues for new comments.

However, sometimes we might miss one or two due to the popularity/high traffic of the repository. We apologize, and kindly ask you to refrain from tagging core maintainers, as that will usually not result in increased priority.

Upvoting issues to show your interest will help us prioritize and address them as quickly as possible. That said, every issue is important to us, and if an issue gets closed by accident, we encourage you to open a new one linking to the old issue and we will look into it.
