Question Unity Firebase SDK Problem

I've installed Unity Firebase SDK, firebase google-services and configured Player Settings with com project name. After that, I've written the following lines of code:

Code (CSharp):

1. private DatabaseReference _databaseReference;
2.     private string _userID;
3.  
4.     private void Start()
5.     {
6.         _databaseReference = FirebaseDatabase.DefaultInstance.RootReference;
7.         _userID = SystemInfo.deviceUniqueIdentifier;
8.     }

Even though I followed the steps from the official documentation, I got an error:
DatabaseException: Failed to get FirebaseDatabase instance: Specify DatabaseURL within FirebaseApp or from your GetInstance() call.
Firebase.Database.FirebaseDatabase.GetInstance (Firebase.FirebaseApp app, System.String url)

Can someone help me please?

 

Looks like you don't have your Firebase json file dowloaded with your database info. If you created your database on Firebase, you also need to redownload the google file that will now contain the database info as well.

 

Am getting the same error even with the Firebase json file downloaded

 

some one realeze this problem ?

 

First i start encounter this problem but i solved using this code in start method


AppOptions options = new AppOptions
{
DatabaseUrl = new System.Uri("https://imposter-killer-955fd-default-rtdb.firebaseio.com/")
};
// Create a new FirebaseApp instance with options
app = FirebaseApp.Create(options);
// Get the FirebaseDatabase instance using the FirebaseApp
firebaseDatabase = FirebaseDatabase.GetInstance(app, "https://imposter-killer-955fd-default-rtdb.firebaseio.com/");


But after working for a while, it encounters again and still i am facing this issue.
