Cannout build production Nextjs

[pascuflow]

Hi, using Nextjs 12.0.9, building fails with :

Error [ERR_REQUIRE_ESM]: Must use import to load ES Module: /foo/node_modules/react-markdown/index.js require() of ES modules is not supported. require() of /foo/node_modules/react-markdown/index.js from /foo/node_modules/@uiw/react-markdown-preview/lib/index.js is an ES module file as it is a .js file whose nearest parent package.json contains "type": "module" which defines all .js files in that package scope as ES modules. Instead rename /foo/node_modules/react-markdown/index.js to end in .cjs, change the requiring code to use import(), or remove "type": "module" from /foo/node_modules/react-markdown/package.json.

If I remove the /foo/node_modules/@uiw/react-markdown-preview/lib/ folder it works, can this be swtiched to esm import syntax?

I tested this instance and there are no errors. You can provide me with an example.
