Eslint invalid extension error.​

ESLint: Invalid Options: - Unknown options: useEslintrc, extensions - 'extensions' has been removed.

If you're encountering an issue caused by a configuration mismatch between ESLint version 9.0.0 and Next.js, it's likely due to compatibility issues. To resolve this, you need to downgrade the ESLint version to 8.57.0.

package.json
{
  "dependencies": {
    // "eslint": "9.12.0",
    "eslint": "8.57.0"
  }
}
