Cannot update a component while rendering a different component. Probably due to bad setState()

[tramax]

Describe the bug React issues a warning about bad setState when the Carousel component is used

To Reproduce Steps to reproduce the behavior:

1. Install 10.2.0
2. Install react-carousel 2.0.3
3. Dynamic import the carousel component like so (as NextJS SSR crashes using normal import)

import dynamic from 'next/dynamic';

const Carousel = dynamic(
  () => import('@brainhubeu/react-carousel'),
  { ssr: false },
);

5. Use the carousel
6. See error in Chrome console

Expected behavior A clear and concise description of what you expected to happen.

I got this working by used the source and removing all the scss imports as they were bugging in my build environment. Simple import of the index.js file from the src directory here https://github.com/brainhubeu/react-carousel/tree/master/react-carousel/src and the errors about setState were resolved.

Hi Shaun. Do you use dynamic import via 'next/dynamic'? Would you be able to post a screenshot or a snippet of your code? Thank you

Hi, sorry I abandoned this in favor of https://github.com/akiran/react-slick that just seems to work our of the box
