Describe the Bug

I tried upgrading my website from v 2.6.4 to 3.0.2 but started getting this error.

unhandledRejection SyntaxError: /Users/jahir/dev/jahir/website/.contentlayer/generated/index.mjs: Support for the experimental syntax 'importAttributes' isn't currently enabled (7:43):

   5 | // NOTE During development Contentlayer imports from `.mjs` files to improve HMR speeds.
   6 | // During (production) builds Contentlayer it imports from `.json` files to improve build performance.

Add @babel/plugin-syntax-import-attributes (https://github.com/babel/babel/tree/main/packages/babel-plugin-syntax-import-attributes) to the 'plugins' section of your Babel config to enable parsing.

What's the expected result?

The build should be completed normal and successfully
