Lines 40 to 47 in ec26a63

	// NOTE workaround for https://github.com/vercel/next.js/issues/17806#issuecomment-913437792
	config.module.rules.push({
	test: /\.m?js$/,
	type: 'javascript/auto',

@schickling vercel/next.js#58967 should already fix this I think, the workaround should no longer be required.
