After installing Prettier, this error has disappeared. What configs do I need to tweak to enable it again?
In the config files .eslintrc.json .prettierignore and .prettierrc, there is no declaration that may affect this. And my dependencies are:

"dependencies": {
    "@formatjs/intl-localematcher": "^0.5.4",
    "negotiator": "^0.6.3",
    "next": "13.4.9",

    "react-dom": "18.2.0",
    "typescript": "5.1.6"
  },
  "devDependencies": {
