FileInput Example is Not Working

I have copy / pasted the example you have online for the FileInput component (removing the DB call to Employee) and when I select a file, I get a "reconnecting to server error" in my browser and a resulting OnError event trigger. Is there a bug with the current FileInput component? All the others seem to be working fine. A screenshot of the error messages (both in ErrorConsole and in the browser dev tools) are seen here:

My code is as follows:

@page "/file-upload"
@attribute [Authorize]

<div class="container-fluid">
    <div class="row px-3">
        <div class="col-lg-6 offset-lg-3 p-3">
            <RadzenCard>
                <RadzenFileInput @bind-FileName=@fileName @bind-FileSize=@fileSize TValue="string" class="w-100"
                                 Change=@(args => OnChange(args, "FileInput")) Error=@(args => OnError(args, "FileInput")) />
            </RadzenCard>
        </div>
    </div>
</div>

<EventConsole @ref=@console />

@code {
    EventConsole console;

    string fileName;
    long? fileSize;

    protected override async Task OnInitializedAsync()
    {
        await base.OnInitializedAsync();
    }

    void OnChange(string value, string name)
    {
        console.Log($"{name} value changed: {value}");
    }

    void OnError(UploadErrorEventArgs args, string name)
    {
        console.Log($"{args.Message}");
    }
}

I am using the same image (a small .PNG) for both the online demo (which works) and my own testing.

You will need to increase your buffer size:
