Operating System: macOS 15.0.1

What did you do?

// eslint.config.ts
import { includeIgnoreFile } from "@eslint/compat";
import js from '@eslint/js';
import tseslint from 'typescript-eslint';
import path from "node:path";

const gitIgnorePath = path.resolve(__dirname, ".gitignore");

module.exports = tseslint.config(
  includeIgnoreFile(gitIgnorePath),
  // ...
}

Run command:

tsc --target esnext --module nodenext eslint.config.ts && eslint . --fix

What did you expect to happen?

Successfully ignoring the paths in .gitignore

What actually happened?

TS say that tseslint.config expects a different return value from includeIgnoreFile(gitIgnorePath):

eslint.config.ts:22:3 - error TS2345: Argument of type 'Config<RulesRecord>' is not assignable to parameter of type 'ConfigWithExtends'.
  The types of 'languageOptions.ecmaVersion' are incompatible between these types.
    Type 'import("/Users/xxx/project/node_modules/.pnpm/[email protected]/node_modules/eslint/lib/types/index").Linter.EcmaVersion' is not assignable to type 'import("/Users/xxx/project/node_modules/.pnpm/@[email protected]/node_modules/@typescript-eslint/types/dist/parser-options").EcmaVersion'.
      Type '16' is not assignable to type 'EcmaVersion'.
