Unable to authenticate using service account

[IlyaSV]

any request with service account auth token return error 403: "Permission denied. Could not perform this operation".

I'm getting this same error unless I change my Firebase Storage rules to allow all read/write. With the default rules (shown below). After I authorize a user via the FirbaseAuthentication.net process, I'm able to read and write to Firebase Database, but not Storage. I'm getting the 403: "Permission denied. Could not perform this operation" error.

Any help is appreciated.

Firebase Storage rules (these are the default rules):
service firebase.storage {
match /b/{bucket}/o {
match /{allPaths=**} {
allow read, write: if request.auth != null;
}
}
}

Firebase Login code (works for reads/writes to Database):

var auth = new FirebaseAuthProvider(new FirebaseConfig(firebaseApiKey));

            var token = await auth.SignInWithEmailAndPasswordAsync(firebaseUsername, firebasePassword);

            
            firebase = new FirebaseClient(
                                    firebaseUrl,
                                    new FirebaseOptions
                                    {
                                        AuthTokenAsyncFactory = () => Task.FromResult(token.FirebaseToken)
                                    });

            loginSuccessfulLabel.Text = "Login Successful";

Firebase storage code to upload .png image file (where 403 error is received). This same code works fine when Firebase storage rules are set to allow all read/write:

async void UploadImage_Clicked(object sender, System.EventArgs e)

        {
            var stream = File.Open("picture2.png", FileMode.Open);

            var task = new FirebaseStorage("xxxxxxx.appspot.com")
                .Child("data")
                .Child("picture2.png")
                .PutAsync(stream);

            task.Progress.ProgressChanged += (s, ex) => Console.WriteLine($"Progress: { ex.Percentage} %");

            downloadURL = await task;
        }

I'm having the same issue. I'm using my firebase server key. Same as when I create a FirebaseClient.
I get this error "Response status code does not indicate success: 403 (Forbidden)."
When I open up the storage rule to allow write: if true; I can save the file. Please help.

private async Task<string> SaveUserPhoto(string uid, Stream photoStream)
        {
            var task = new FirebaseStorage(_StorageBucket, new FirebaseStorageOptions()
                {
                    AuthTokenAsyncFactory = () => Task.FromResult(_firebaseServerKey)                    
                })
                .Child("residentPhotos")
                .Child(uid)
                .Child("profile.jpg")
                .PutAsync(photoStream);

            // Track progress of the upload
            task.Progress.ProgressChanged += (s, e) => Console.WriteLine($"Progress: {e.Percentage} %");

            // await the task to wait until upload completes and get the download url
            var downloadUrl = await task;

            return downloadUrl;
        }

I was able to authenticate using a user account. just follow the simpleConsole sample code. I would still be nice to use some type of service account.
