Ошибка an unhandled exception occurred while processing the request - ErrorsMaster.ru - большая энциклопедия ошибок и их решений

So, I’m trying to implement OpenIddict version 1.0.0-beta2-0580 with NET core 1.1 and I get the following error:

An unhandled exception occurred while processing the request

This is based on this : https://github.com/openiddict/openiddict-core/tree/dev/samples

The db registers the database correctly, the settings is loaded and everything works here. The tables in the db: __efmigrationshistory, aspnetroleclaims, aspnetroles, aspnetuserclaims, aspnetuserlogins, aspnetuserroles, aspnetusers, aspnetusertokens, basetransaction, openiddictapplications, openiddictauthorizations, openiddictscopes, openiddicttokens

And then I have the following stack trace :

InvalidOperationException: The authentication ticket was rejected because the mandatory subject claim was missing.

In the startup I have :

// This method gets called by the runtime. Use this method to add services to the container.
public void ConfigureServices(IServiceCollection services)
{
    // Add framework services.
    services.AddMvc();

    services.RegisterDatabase(aspNet: true, useOpenIddict : true);

    // Register the Identity services.
    service.AddIdentity<User, IdentityRole>(config => { config.SignIn.RequireConfirmedEmail = requireConfirmEmail; })
          .AddEntityFrameworkStores<DatabaseContext>()
          .AddDefaultTokenProviders();

    services.AddOpenIddict(options =>

        // Register the Entity Framework stores.
        options.AddEntityFrameworkCoreStores<DatabaseContext>();

        //
        // options.UseJsonWebTokens();
        // options.AddEphemeralSigningKey();
    });
}

And then at the configure I have this :

// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IServiceProvider service, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
    app.UseOpenIddict();

    // Create a new service scope to ensure the database context is correctly disposed when this methods returns.
    using (var scope = service.GetRequiredService<IServiceScopeFactory>().CreateScope())
    {
        var context = scope.ServiceProvider.GetRequiredService<DatabaseContext>();

        await context.Database.MigrateAsync();

        OpenIddictApplicationManager<OpenIddictApplication> manager = scope.ServiceProvider.GetRequiredService<OpenIddictApplicationManager<OpenIddictApplication>>();

        // ---- Delete code comment ----------

        // * Client secret: [blank] (not used with public clients)
        // * Scope: openid email profile roles
        // * Grant type: authorization code
        // * Request access token locally: yes
        var client = await manager.FindByClientIdAsync("postman", cancellationToken); 

        if (client == null)
        {
            var application = new OpenIddictApplication
            {
                ClientId = "postman",
                DisplayName = "Postman",
            };
            await manager.CreateAsync(application, cancellationToken);
        }
    }


    if (env.IsDevelopment())
    {
        app.UseDeveloperExceptionPage();
        app.UseBrowserLink();
    }
    else
    {

Question
User-190697402 posted

Hi ,

Im getting this error after trying to add Assets to StaffAssets table
```
InvalidOperationException: The instance of entity type 'StaffAssets' cannot be tracked because another instance with the same key value for {'StaffID'} is already being tracked. When attaching existing entities, ensure that only one entity instance with a given key value is attached. Consider using 'DbContextOptionsBuilder.EnableSensitiveDataLogging' to see the conflicting key values.
```
Here is what i have to acheive, My Assets tab will have Create New button,when i click on that it should navigate to Add Screen,

I should be able to add the assets for the employee

I should be able to add multiple Assets.Whats happening now is,when i add assets for the first its inserting record to StaffAssets table,but when im adding it for the second time,im getting the above mentioned error.

Hi,teenajohn1989

If your problem is save the input data but show the last input data, then I have reproduced it.

You just need to put the query sentence into ‘if’ method, like my demo:
```
public async Task<IActionResult> OnPostInsertAssetsDetailsAsync(int current = 3)
        {
            if (ModelState.GetFieldValidationState("StaffAssets") == ModelValidationState.Valid)
            {
                await _context.StaffAssets.AddAsync(StaffAssets);
                await _context.SaveChangesAsync();
                //when add works, then +1 ,means next tab
                currentTab = current;
                TempData["EmpID"] = StaffAssets.EmpID;
                TempData["StaffID"] = StaffAssets.StaffID;
                ShowStaffAssets = _context.StaffAssets.Where(c => c.StaffAssetName == StaffAssets.StaffAssetName).AsNoTracking().ToList();
                return Page();
            }
            else
            {
                var errors = ModelState.Values.SelectMany(v => v.Errors);
                return Page();
            }
        }
```
Result:

Hi,teenajohn1989

What is ‘not populate the already inserted one’ while you want to show all the added data means?

If you want to show all the assets, you just need to change the query in my demo to yours :
```
ShowStaffAssets = _context.StaffAssets.Where(c => c.StaffID == StaffAssets.StaffID).ToList();
```
Result:

If anything still wrong , you can share your create method, I’m not sure what you did in it.
```
<input type="button" class="btn-success" id="OnClickCreateStaffAsset" value="Create New" />
```

Hi Jerry Cai,

The display issue is fixed now.what i did is just add AsNoTracking() in the query
```
ShowStaffAssets =  _context.StaffAssets.Where(c => c.StaffID == StaffAssets.StaffID).OrderBy(c => c.StaffAssetName).AsNoTracking().ToList();
               
```
Thank you so much for the endless support and letting me know how to debug the LINQ query also.

Describe the bug

After adding another Asp.Net Core WebApi project to a Blazor WebAssembly Hosted solution, and adding [Authorize] attribute to a controller, the new WebApi project fails to start with:
An unhandled exception occurred while processing the request.
InvalidOperationException: No authenticationScheme was specified, and there was no DefaultChallengeScheme found. The default schemes can be set using either AddAuthentication(string defaultScheme) or AddAuthentication(Action configureOptions).
Microsoft.AspNetCore.Authentication.AuthenticationService.ChallengeAsync(HttpContext context, string scheme, AuthenticationProperties properties)

To Reproduce

Create a new Blazor WebAssembly project
Change Authentication to ‘Individual User Accounts’ and select ‘Store user accounts in-app’
Make sure ASP.Net Core hosted is checked (true)
Run update-database in Package Manager Console to add the Asp.net Identity and IdentityServer4 tables
Register an account
Add a new Asp.Net Core WebApi project to the solution
Add [Authorize] attribute to WeatherForecast controller
Add CORS and allow the Client origin
Add authentication and authorization
` services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme);
//services.AddAuthentication(options =>
//{
// options.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;
// options.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;
//});
services.AddAuthorization();

        app.UseAuthentication();
        app.UseAuthorization();

`
10) Back in the Client project make a copy of Fetch.razor
11) In the copy of Fetch.razor inject or create a new HttpClient that has the base address of the new WebApiProject
12) Build and run the new WebApi project and get error:
An unhandled exception occurred while processing the request.
InvalidOperationException: No authenticationScheme was specified, and there was no DefaultChallengeScheme found. The default schemes can be set using either AddAuthentication(string defaultScheme) or AddAuthentication(Action configureOptions).
Microsoft.AspNetCore.Authentication.AuthenticationService.ChallengeAsync(HttpContext context, string scheme, AuthenticationProperties properties)

Tried:
services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme);
and
services.AddAuthentication(options => { options.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme; options.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme; });
with same exception.

What is required to configure additional WebApi projects for the new IdentityServer4 / Asp.Net Identity authentication / authorization?

Exceptions (if any)

An unhandled exception occurred while processing the request.
InvalidOperationException: No authenticationScheme was specified, and there was no DefaultChallengeScheme found. The default schemes can be set using either AddAuthentication(string defaultScheme) or AddAuthentication(Action configureOptions).
Microsoft.AspNetCore.Authentication.AuthenticationService.ChallengeAsync(HttpContext context, string scheme, AuthenticationProperties properties)

Я изучал возможности использования сборок в Asp.net core и наткнулся на одну проблему. При попытке вызвать метод точки входа в приложение, использующее контекст данных для связи с БД выкидывает ошибку. Контекст оформлен как сервис.

Как правильно использовать БД внутри загружаемой сборки?
Загрузка сборки

public void ConfigureServices(IServiceCollection services)
        {
            executableLocation = Assembly.GetEntryAssembly().Location;
            var path = Path.Combine(Path.GetDirectoryName(executableLocation), "Plugins");
            var assemblies = Directory
                    .GetFiles(path, "*.dll", SearchOption.AllDirectories)
                    .Select(AssemblyLoadContext.Default.LoadFromAssemblyPath)
                    .ToList();

Recently, I came across an interesting problem. Whenever we run my ASP.NET Core application in Development environment, I get the below exception.

Details about the setup:

The below template was used:

Angular project template with ASP.NET core — https://docs.microsoft.com/en-us/aspnet/core/client-side/spa/angular?view=aspnetcore-2.2&tabs=visual… along with AAD integration.

When we publish this application in Azure App Service, it works fine. But when we run the same application in Visual Studio, it fails with the below error.

An unhandled exception occurred while processing the request.IOException: The server returned an invalid or unrecognized response.
System.Net.Http.HttpConnection.FillAsync()HttpRequestException: An error occurred while sending the request.

It took almost a whole day for me to narrow down the problem:

The AAD auth settings and configurations both in the azure portal as well as the app is correct.
The auth flow is same between the working and non-working scenarios.
We compared the headers, cookies, tokens etc. very closely between working and non-working cases and nothing is different.
We captured the log statement from the .net core and har file and cookie sent and received are all the same.
The concerning error was misleading “The server returned an invalid or unrecognized response.”, digging further we identified it was actually a HTTP 400 error underneath.

Sample log file:

The actual issue:

We identified that, in development, requests are proxied to the Angular development server that gets started as a background process which is a Node.JS server which has a header limit of ~8kb. Hence, it is failing with 400 error.

Refer: https://nodejs.org/en/blog/vulnerability/november-2018-security-releases/#denial-of-service-with-lar…

Recommendation:

So, if you want to use AAD auth in development environment you’re going to need to slim down the cookie, likely by filtering out unneeded claims. There’re some related docs here:

Refer: https://docs.microsoft.com/en-us/aspnet/core/security/authentication/social/additional-claims?view=a…

Also, we can install latest Nodejs that supports increasing the header size.

Refer: https://github.com/nodejs/node/blob/master/doc/changelogs/CHANGELOG_V10.md

Note: This issue impacts any project template that uses the following.

ASP.NET core + Angular + AAD (OAuth)

ASP.NET core + React + AAD (OAuth)
