Link to minimal reproduction or a simple code snippet

<FilePicker Changed="OnFileChanged" Filter="image/*" MaxFileSize="MaxFileSize" AutoReset="true" DisableProgressReport="true" />

private async Task OnFileChanged(FileChangedEventArgs e)
{
    try
    {
        foreach (var file in e.Files)
        {
            if (file.Status == FileEntryStatus.Error)
            {
                await Toast.Error(file.ErrorMessage);
            }
            else if (file.Status == FileEntryStatus.ExceedsMaximumSize)
            {
                await Toast.Warning("File size is too large");
            }
            else if (file.Status == FileEntryStatus.Ready)
            {
                var buffer = await GetBuffer(file);
                ShowPicture(file, buffer);
            }
        }
    }
    catch (Exception ex)
    {
        ex.ProcessException(Toast, Logger);
    }
}

Steps to reproduce & bug description

select a file (this error does not happen on localhost, only on the server)

What is expected?

call the method with the file and do what needs to be done.

What is actually happening?

I think the method is not being called. There is an error occurring at the javascript level.

What browsers do you see the problem on?

Chrome

Any additional comments?

No response

Working on it #6032

[drma-tech]

So it will only come out in 1.8? When is this version expected to come out?

[stsrki]

The fix will come in 1.7.

The proper "non-dirty" fix will be in 1.8.

Hi everyone, I've already updated to version 1.8.0 and I'm having the same problem. When I try to select a file in the browser's Debug Console, it shows me these errors. Has the problem been resolved yet?

[guillaumebaril]

I do have the same exact issue on 1.8.0, only when my app is deployed to azure

[guillaumebaril]

Other info: I can fix my issue if I add the nuget
<PackageReference Include="Syncfusion.Blazor.DropDowns" Version="28.2.11" />

and add SyncFusionBlazor to my services
builder.Services.AddSyncfusionBlazor();

which doesn't really make sense

That's weird to say the least 😅

---

The main issue is that I couldn't reproduce it any time again. I was able to do it once only, and after that whatever I did I couldn't make it to break.
