Motivation/ Context
nextfrom11to12, I followed Upgrade guide from 11 => 12. I removed.babelrcto opt-inSWC. I thought that's all, but after removing.babelrc, Jest broke immediately. So I follow the guide https://nextjs.org/docs/advanced-features/compiler#jest to configure Jest to work with SWC. I copied the content ofjest.config.jsto my project but it does not work. The reason:Documentation
pnpm lintFuture work
.babelrcto opt-in SWC. The current Jest settings will crash (since it's using babel). We likely want to update the Upgrade guide to mention this cc: @leerob
