The import path 'eslint/config' and the functions defineConfig and globalIgnores don't appear to be part of the standard ESLint 9.x API.

According to the ESLint flat config documentation, the correct approach is:

  1. Export a plain array or object directly (no defineConfig wrapper needed)
  2. Use { ignores: [...] } as a config object, not globalIgnores([...])

Standard ESLint 9 flat config should look like:

export default [
  ...nextVitals,
  ...nextTs,
  {
    ignores: ['.next/**', 'out/**', 'build/**', 'next-env.d.ts', 'node_modules/**']
  }
];

Please verify that this configuration actually works in your environment, as the current syntax doesn't match ESLint's official flat config specification.
