Describe the Bug

My NextJS config is setup as a function, as outlined here - https://nextjs.org/docs/app/api-reference/next-config-js

E.g.:

const MillionLint = require('@million/lint')

const nextConfig = async (phase, { defaultConfig }) => {
  const config = {
    /* config options here */
  }
  return config
}

module.exports = MillionLint.next({ rsc: true })(nextConfig)

Looking at the source of Million, it appears that this is not a supported configuration option.

What's the expected result?

I expected Million to accept the configuration.

I quickly realised the workaround. Simply wrap the return for the function instead. E.g.:

const MillionLint = require('@million/lint')

const nextConfig = async (phase, { defaultConfig }) => {
  const config = {
    /* config options here */
  }
  return MillionLint.next({ rsc: true })(config)
}

module.exports = nextConfig

It would be good to document this.
