  hi

  namespace Volo.Abp.AspNetCore.Mvc.UI.Theme.Lepton.Views.Error.DefaultErrorComponent;
  public class LeptonErrorViewComponent
  

  Volo.Abp.AspNetCore.Mvc.UI.Theme.Lepton/Views/Error/DefaultErrorComponent/LeptonErrorViewComponent.cs

  We are looking to change only the html on the error page. So we followed the instructions here: https://docs.abp.io/en/abp/latest/UI/AspNetCore/Customization-User-Interface#overriding-a-razor-page-cshtml

  In following those instructions, we created a modified Default.cshtml under the same folder structure in our project as defined in Abp (see below). The problem is though that we don't see our changes and the Abp error page still shows. Any ideas?

  Also, LeptonErrorViewComponent's Invoke method is not overridable (virual) so the component cannot be replaced.

  hi

  You can create your LeptonErrorViewComponent and use it here.

  We created our own nVisionLeptonErrorViewComponent and added our own 404.cshtml

  Our project solution is as follows:

  Our 404.cshtml is as follows:

  @using FM.nVision.Blazor.Views.Error.DefaultErrorComponent;
  @using Volo.Abp.AspNetCore.Mvc.UI.Theme.Lepton.Views.Error.DefaultErrorComponent
  @model Volo.Abp.AspNetCore.Mvc.UI.Theme.Shared.Views.Error.AbpErrorViewModel
  
  @(await Component.InvokeAsync&ltnVisionLeptonErrorViewComponent&gt(new { model = Model, defaultErrorMessageKey = "404Message" }))
  

  Our nVisionLeptonErrorViewComponent is as follows:

  using Volo.Abp.AspNetCore.Mvc.UI.Theme.Lepton.Views.Error.DefaultErrorComponent;
  
  namespace FM.nVision.Blazor.Views.Error.DefaultErrorComponent;
  
  public class nVisionLeptonErrorViewComponent : LeptonViewComponentBase
  {
      public IViewComponentResult Invoke(AbpErrorViewModel model, string defaultErrorMessageKey)
      {
          var leptonModel = new LeptonErrorPageModel
          {
              ErrorInfo = model.ErrorInfo,
              HttpStatusCode = model.HttpStatusCode,
              DefaultErrorMessageKey = defaultErrorMessageKey
          };
  
          return View("~/Views/Error/DefaultErrorComponent/Default.cshtml", leptonModel);
      }
  }
  

  We still don't see our custom Default.cshtml in Views/Error/DefaultErrorComponent. Is there something else we are missing?

  Interesting... I have the same setup. Could it be because I'm using a Blazor Server templated solution and your using MVC?
