    When you get in undefined from firebaseConfig object value of keys. And they given a error like FirebaseError: Firebase: Error (auth/invalid-api-key). but your environment variable name and process.env.[environment variable name] and you had create a .env file root directory but stll they given same error.

    The Answer is .. You have to do right now, your terminal again restart when you still the same error..

    this solution is worked my problem.
