  We will fix it, your ticket refunded.

  For now, you can try:

  [ExposeServices(typeof(DynamicWidgetMarkdown))]
  public class MyDynamicWidgetMarkdown : DynamicWidgetMarkdown
  {
      [Inject]
      protected IOptions<AbpRemoteServiceOptions> RemoteServiceOptions { get; set; }
  
      protected override async Task OnImageUploadChangedAsync(FileChangedEventArgs e)
      {
          try
          {
              if (e.Files.Length > 1)
              {
                  return;
              }
  
              foreach (var file in e.Files)
              {
                  UploadImages[file.Id] = new MemoryStream();
                  await file.WriteToStreamAsync(UploadImages[file.Id]);
  
                  if (!Value.IsNullOrWhiteSpace())
                  {
                      await MarkdownRef.SetValueAsync(Value.Replace("Placeholder.jpg", string.Empty));
                  }
              }
          }
          catch (Exception exception)
          {
              await HandleErrorAsync(exception);
          }
      }
  
      protected override async Task OnImageUploadEndedAsync(FileEndedEventArgs e)
      {
          using (var stream = UploadImages[e.File.Id])
          {
              stream.Position = 0;
              var result = await MediaDescriptorAdminAppService.CreateAsync(BlogPostConsts.EntityType, new CreateMediaInputWithStream
              {
                  Name = e.File.Name,
                  File = new RemoteStreamContent(stream, e.File.Name, e.File.Type)
              });
  
              var baseUrl = RemoteServiceOptions.Value.RemoteServices.GetConfigurationOrDefaultOrNull(CmsKitAdminRemoteServiceConsts.RemoteServiceName).BaseUrl;
              e.File.UploadUrl = $"{baseUrl}/api/cms-kit/media/{result.Id}Placeholder.jpg";
  
              UploadImages.Remove(e.File.Id);
          }
      }
  }

  The new implementation of DynamicWidgetMarkdowndoes not work either.

  steps to repeat this error with this new file:

  1. I created again a brand new solition using the Blazor Server + SQLite template

  2. run the DbMigration

  3. create new blog

  4. create new blogpost

  5. upload an image in the bogpost content body.

  6. Visual Studio will hit my breakpoint in MyDynamicWidgetMarkdown.OnImageUploadChangedAsync (so the new implementation is used)

  7. nothing happens, but after 30 seconds, my breakpoint at the first line in MyDynamicWidgetMarkdown.OnImageUploadEndedAsync is hit (at this moment the blazor code gives no error, but the browser gives the error below

  

  At this moment the logfile ends with:

  2023-01-14 16:18:19.067 +01:00 [INF] Sending file. Request path: '/_content/Blazorise/io.js'. Physical path: 'C:\Users\info\.nuget\packages\blazorise\1.1.4.1\staticwebassets\io.js'

  8. when I step through my code, after executing the line with await file.WriteToStreamAsync(UploadImages[file.Id]); my visual studio breaks the application with the error below.

  

  No additional information is added to the logfile

  I hope this five

  Hi.

  It looks not a problem with ABP, but Blazor: See: https://github.com/dotnet/aspnetcore/issues/38842#issuecomment-1342540950

  You can try this:

  Configure<HubOptions>(options =>
  {
      options.DisableImplicitFromServicesParameters = true;
  });

  We are a little bit closer to the solution. At this moment I am still not able to post an image due to a poblem in the suggested MyDynamicWidgetMarkdown

  The line 59 below will cause an 'Object reference not set to an instance of an object.', because GetConfigurationOrDefaultOrNull(CmsKitAdminRemoteServiceConsts.RemoteServiceName) is returning null

  Hi,

  Sorry, I thought you were using Blazor webassembly.

  try:

  [ExposeServices(typeof(DynamicWidgetMarkdown))]
  public class MyDynamicWidgetMarkdown : DynamicWidgetMarkdown
  {
      protected override async Task OnImageUploadChangedAsync(FileChangedEventArgs e)
      {
          try
          {
              if (e.Files.Length > 1)
              {
                  return;
              }
  
              foreach (var file in e.Files)
              {
                  UploadImages[file.Id] = new MemoryStream();
                  await file.WriteToStreamAsync(UploadImages[file.Id]);
  
                  if (!Value.IsNullOrWhiteSpace())
                  {
                      await MarkdownRef.SetValueAsync(Value.Replace("Placeholder.jpg", string.Empty));
                  }
              }
          }
          catch (Exception exception)
          {
              await HandleErrorAsync(exception);
          }
      }
  
      protected override async Task OnImageUploadEndedAsync(FileEndedEventArgs e)
      {
          using (var stream = UploadImages[e.File.Id])
          {
              stream.Position = 0;
              var result = await MediaDescriptorAdminAppService.CreateAsync(BlogPostConsts.EntityType, new         CreateMediaInputWithStream
              {
                  Name = e.File.Name,
                  File = new RemoteStreamContent(stream, e.File.Name, e.File.Type)
              });
              
              e.File.UploadUrl = $"/api/cms-kit/media/{result.Id}Placeholder.jpg";
  
              UploadImages.Remove(e.File.Id);
          }
      }
  }
  

  There is also a new problem when you edit a blog post, we have fixed it.
