ESLint: TypeError: this.libOptions.parse is not a function

Question

I was getting started with Next.js on WebStorm 2022.2.1 Build #WS-222.3739.57. I created a new Next.js project with TypeScript enabled, and that's all.

The error is shown below:

TypeError: this.libOptions.parse is not a function

My Node.js version is v16.15.1, and the ESLint version is 8.23.0.

This is what my devDependencies look like;

  "devDependencies": {
    "@types/node": "18.7.13",
    "@types/react": "18.0.17",
    "@types/react-dom": "18.0.6",
    "eslint": "8.23.0",
    "eslint-config-next": "12.2.5",
    "prisma": "^4.2.1",
    "typescript": "4.8.2"
  }

My .eslintrc.json file:

{
  "extends": "next/core-web-vitals"
}

The issue is tracked at WEB-57089, and it is fixed in 2022.2.2 preview build.

The issue is caused by the changes introduced in ESLint 8.23 (offending upstream commit: View on GitHub). Downgrading ESLint to 8.22.x or earlier (with npm install eslint@8.22.0 --save-exact) should help.
