So i’ve just setup an app for the first time on GoogleDrive with the hope of using it as a back end for file storage for an application i’m developing. I just wanted to get some of the Google Drive basis out of the way, like listing files, uploading and renaming but I cannot even get past the Auth.

I have setup a most basic Blazor Server app with the below code. It causes a browser to open with the below error.

@code {

    string[] Scopes = { DriveService.Scope.DriveReadonly };
    string ApplicationName = "Drive API .NET Quickstart";

    UserCredential credential;

    protected override async Task OnParametersSetAsync()
    {
        // credentials.json points to the file containing the client ID and client secret.
        var clientSecrets = await GoogleClientSecrets.FromFileAsync("client_secret.json");

        credential = await GoogleWebAuthorizationBroker.AuthorizeAsync(
            clientSecrets.Secrets,
            new[] { DriveService.ScopeConstants.DriveFile },
            "user",
            CancellationToken.None);

        var driveService = new DriveService(new BaseClientService.Initializer()
            {
                HttpClientInitializer = credential
            });
    }
}

I have however, set the redirect uri in the google console, I also made sure to download the new Secret.json file. However, I also noticed that the port listed in the attached screenshot changes every single time I run the app so no matter what I would do, this error will always come back?

I understand that there are many similar posts but I’ve never seen one mention that the port is always being rotated?

Is there a better way to do this in 2024?
