Description

When using JSRuntime.InvokeAsync<byte[]>("readByteArray") in BlazorServer, the following exception occurs:

Microsoft.JSInterop.JSException: An exception occurred executing JS interop: JSON serialization is attempting to deserialize an unexpected byte array.. See InnerException for more details.
---> System.Text.Json.JsonException: JSON serialization is attempting to deserialize an unexpected byte array.

In TargetFramework 7.0 and ABP 7.3.0, it is an exception, in TargetFramework 6.0 and ABP 6.0.3, it is normal, but in TargetFramework 7.0 and ABP 6.0.3, it is an exception.

The BlazorServer template provided by ABP also has the same problem. I used the BlazorServer template provided by dotnet and used ABP in the smallest way, only referencing the Volo.Abp.Autofac package, and the problem is the same.

How about without abp?

hi

How about without abp?

When the code related to ABP is commented out, it can work correctly.

using BlazorServerTestProject;
using BlazorServerTestProject.Data;
using Volo.Abp;

var builder = WebApplication.CreateBuilder(args);

// Abp
// builder.Host.UseAutofac();
// builder.Services.AddApplication<BlazorServerModule>();

// Add services to the container.
builder.Services.AddRazorPages();
builder.Services.AddServerSideBlazor();
builder.Services.AddSingleton<WeatherForecastService>();

var app = builder.Build();

// Configure the HTTP request pipeline.
if (!app.Environment.IsDevelopment())
{
    app.UseExceptionHandler("/Error");
    // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
    app.UseHsts();
}

app.UseHttpsRedirection();

app.UseStaticFiles();

app.UseRouting();

app.MapBlazorHub();
app.MapFallbackToPage("/_Host");

app.Run();

Your test code gets 404 error first.
