This is identical to PR https://github.com/react-chess/chessground/issues/13. I'm experiencing the same issue on a blank Next.js project. `npx create-next-app --example with-docker nextjs-docker` `cd nextjs-docker` `npm i @react-chess/chessground` Add the `import` commands and a `<Chessground />` then run `npm run dev` to replicate. Help is much appreciated!
