Lost on parserPath or languageOptions.parser is required

[AdditionAddict]

I had .eslintrc.cjs

/** @type {import('eslint').Linter.Config} */
module.exports = {

This is basic remix example plus some ignores

Running the migrate got me eslint.config.mjs:

    languageOptions: {

But I'm getting a bunch of parserPath or languageOptions.parser is required! errors

/Users/andrew/extruda/extruda-supabase/apps/supervisor-app/app/site-instruction/$id.edit.tsx

I can't find any result for parserPath or languageOptions.parser on the website so I'm a bit confused what's required here.

These all come from eslint-plugin-import. You'll need to ask the maintainers of that plugin for help.
