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..
