Identity Server 4 request validation failed because of invalid scopes - authentication

Question

first time seeking help here so I hope i will explain my problem on proper way.
I have a .NET Core 3.0 MVC application up and running and I was trying to add a Identity Server 4 authentication to it. I'm struggling for hours with the following problem.
Sorry, there was an error : invalid_scope
Invalid scope
In the log I got this message
[ERR] Invalid scope: profile
[ERR] Request validation failed
Line bellow that In the info log when checking for scopes I found this JSON objects, and can't see whats problem here.
"scope":"openid profile",
"RequestedScopes":"openid profile"
Here is the config.cs file of the Identity Server project
public static IEnumerable<IdentityResource> Ids =>
new IdentityResource[]
{
new IdentityResources.OpenId()
};
public static IEnumerable<ApiResource> Apis =>
new ApiResource[]
{ };
public static IEnumerable<Client> Clients =>
new Client[]
{
new Client
{
ClientId = "mvc",
ClientName = "Festival MVC",
AllowedGrantTypes = GrantTypes.Implicit,
RedirectUris = { "https://127.0.0.1:44330/signin-oidc" },
PostLogoutRedirectUris = { "https://127.0.0.1:44330/signout-callback-oidc" },
AllowedScopes = { IdentityServerConstants.StandardScopes.OpenId }
}
};
}
Startup.cs
public void ConfigureServices(IServiceCollection services)
{
// uncomment, if you want to add an MVC-based UI
services.AddControllersWithViews();
var builder = services.AddIdentityServer()
.AddTestUsers(TestUsers.Users)
.AddInMemoryIdentityResources(Config.Ids)
.AddInMemoryApiResources(Config.Apis)
.AddInMemoryClients(Config.Clients);
// not recommended for production - you need to store your key material somewhere secure
builder.AddDeveloperSigningCredential();
}
public void Configure(IApplicationBuilder app)
{
if (Environment.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
// uncomment if you want to add MVC
app.UseStaticFiles();
app.UseRouting();
app.UseIdentityServer();
// uncomment, if you want to add MVC
app.UseAuthorization();
app.UseEndpoints(endpoints =>
{
endpoints.MapDefaultControllerRoute();
});
}
On the .NET Core MVC project I configured the follow in Startup.cs
public void ConfigureServices(IServiceCollection services)
{
JwtSecurityTokenHandler.DefaultInboundClaimTypeMap.Clear();
services.AddAuthentication(options =>
{
options.DefaultScheme = "Cookies";
options.DefaultChallengeScheme = "oidc";
})
.AddCookie("Cookies")
.AddOpenIdConnect("oidc", options =>
{
options.SignInScheme = "Cookies";
options.Authority = "http://localhost:5000"; // Auth Server
options.RequireHttpsMetadata = false; // only for development
options.ClientId = "mvc"; // client setup in Auth Server
options.SaveTokens = true;
});
services.AddControllersWithViews();
services.AddDbContext<FestivalContext>();
}
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
else
{
app.UseExceptionHandler("/Home/Error");
app.UseHsts();
}
app.UseHttpsRedirection();
app.UseStaticFiles();
app.UseAuthentication();
app.UseRouting();
app.UseAuthorization();
app.UseEndpoints(endpoints =>
{
endpoints.MapControllerRoute(
name: "default",
pattern: "{controller=Home}/{action=Index}/{id?}");
});
}
}
If you need any other info or code snippet feel free to post.
Thanks in advance and greetings,
Anes !
