@flpmswap Thanks for the report. I can confirm that this is a valid bug & I'm able to reproduce.

This issue seems to be introduced via https://github.com/eslint/create-config/pull/156

The issue is that defineConfig was exported recently in v9.22, but the project generated is using v8

I'll work on it, moving this to eslint/create-config.

Hi @snitin315 this continues to be an issue also for ESLINT + typescript .

Actually you should drop the TS support from this config generator because once selected the ESLint versions on the deps defaults to 8.x that is the only one that "name": "typescript-eslint", supports

See its package file here :

"dependencies": {
    "@typescript-eslint/eslint-plugin": "8.32.1",
    "@typescript-eslint/parser": "8.32.1",
    "@typescript-eslint/utils": "8.32.1" -> these dont support eslint 9.x 
  },
  "peerDependencies": {
    "eslint": "^8.57.0 || ^9.0.0", -> ok here 
    "typescript": ">=4.8.4 <5.9.0"
  },
