ESLint: Failed to load config "@repo/eslint-configuration/.eslintrc.nextjs.cjs" to extend from.

I'm working on a Turborepo with an ESLint package. This error gets raised at build and not at dev. Any help welcome.

apps/next-app-boilerplate/.eslintrc.cjs
/** @type {import("eslint").Linter.Config} */
const config = {
  ignorePatterns: ["apps/*", "packages/*"],
  extends: ["@repo/eslint-configuration/.eslintrc.nextjs.cjs"],
};

module.exports = config;


"@repo/eslint-configuration": "*" is added as a devDependency to apps/next-app-boilerplate/package.json

packages/eslint-configuration/.eslint.nextjs.cjs
/** @type {import("eslint").Linter.Config} */
const config = {
    extends: [
      "next/core-web-vitals",
      "@repo/eslint-config/.eslintrc.base.cjs"
    ],
  };
  
  module.exports = config;


packages/eslint-configuration/package.json
{
    "name": "@repo/eslint-configuration",
    "version": "0.0.0",
    "private": true,
    "files": [
        ".eslintrc.base.cjs",
        ".eslintrc.nextjs.cjs"
    ],
    "dependencies": {
        "@types/eslint": "^8.56.2",
        "eslint": "^8.56.0"
    },
    "devDependencies": {
        "@typescript-eslint/eslint-plugin": "6.18.1",
        "@typescript-eslint/parser": "6.18.1",
        "eslint-config-next": "^14.0.4"
    }
}
Solution
Changing .eslint.nextjs.cjs -> .eslint.nextjs.js fixed it for me.
