[REQUIRED] Please fill in the following fields:

• Unity editor version: 2020.3.14f1 LTS
• Firebase Unity SDK version: 8.1.0

• Platform you are using the Unity editor on: Windows

[REQUIRED] Please describe the issue here:

We are performing a very simple query which gets from the Firestore database a document, which comes in a DocumentSnapshot format and we are trying to convert it to a ScriptableObject, everything works just right, but there's this annoying warning in the Unity console which we can't get rid of and we were wondering if there's anything we might be doing wrong.

Steps to reproduce:

Have you been able to reproduce this issue with just the Firebase Unity quickstarts (this GitHub project)? No
What's the issue repro rate? 100%

What happened?

Log trace: BidInstanceData must be instantiated using the ScriptableObject.CreateInstance method instead of new BidInstanceData.

How can we make the problem occur?
Yes, just retrieve a document from the database and try to convert it to a ScriptableObject.

Relevant Code:

    IEnumerator ManageUserCreation()
    {
        //Get the user from the DB
        Task<DocumentSnapshot> userInDB = GetUserFromDB();

        //Wait till completed
        yield return new WaitUntil(() => userInDB.IsCompleted);

        if (userInDB.Exception != null)
            yield break;

        //Does the user exist?
        bool exists = userInDB.Result.Exists;
        if(!exists)
        {
            Debug.Log("User does not exist, creating...");

            //Create the user
            CreateUser();
        }
        else
        {
            Debug.Log("User exists, information retrieved.");

            //Assign info to player
            m_Player = userInDB.Result.ConvertTo<PlayerData>(); // <<<<===== This line generates the warning.
        }
    }

@cgascons Can you clarify if you're using Realtime Database or Firestore? You've specified "database" but the code looks like Firestore. Could you update your code sample to include any relevant "using" declarations? That would also help disambiguate. Oh, and could you include the definition of the PlayerData class and GetUserFromDB() method?

@dconeybe Sorry, you are right, we are using Firestore db.
I will prepare a sample and get it ready ASAP. Will post it here.

Ok, we have been able to create a standalone project and have uploaded it to this wetransfer link.
Steps:
1 - You will need to just create a test project in firebase with authentication by email and a firestore database.
2- I have deleted from the sample project the configuration files (google-services.json) for security reasons, remember to add them into /Assets folder.
3 - Run the project, it will automatically create a user in Firebase Auth and after that it will check if there's a user inside Firestore's "users" custom collection. If there's not such user it will create it,
4 - Click on the "Retrieve user from Firestore" button shown in the canvas which is the one that will cause the warning we mentioned.
Thanks
