Cache entry must specify a value for Size when SizeLimit is set.

[Evokati]

So, I have a .net 6 MVC project. And I need to replace DevExpress reports with Stimulsoft.

I added package Stimulsoft.Reports.Web.NetCore
Added a DesignerController:

Code: Select all

public class DesignerController : Controller
{
	public IActionResult Index()
	{
		return View("StiDesigner");
	}

	public IActionResult GetReport()
	{
		var report = new StiReport();
		report.Load(StiNetCoreHelper.MapPath(this, "Reports/MyTwoSimpleLists.mrt"));

		return StiNetCoreDesigner.GetReportResult(this, report);
	}

	public IActionResult DesignerEvent()
	{
		return StiNetCoreDesigner.DesignerEventResult(this);
	}
}

Then added a view:

Code: Select all

@using Stimulsoft.Report.Mvc

@{
    ViewBag.Title = "StiDesigner";   
}


@Html.StiNetCoreDesigner(new StiNetCoreDesignerOptions()
{
    Actions =
    {
        GetReport = "GetReport",
        DesignerEvent = "DesignerEvent"
    }
}) 

When I try to open that view I see an error in the browser console:
https://localhost:44364/Designer/Design ... nerScripts net::ERR_ABORTED 500 (Internal Server Error)

The error is thrown on this line:
return StiNetCoreDesigner.DesignerEventResult(this);
inside DesingerController

The whole call stack:

Code: Select all

When I try to do the same inside a new project everything works fine. So, I guess there is something inside my project that causes that. It's pretty old (was originally written in .net framework then migrated to .net 6).
But I have no idea where to look? I'd appreciate any help.

Hello,

Please send us the project configuration (ConfigureServices method), and other similar information on project configuration.
This error means that your project has a cache size limit set somewhere, it should be removed for correct functioning.
or another option is to use a session for caching reports (Server.CacheMode property of the viewer).

Thank you.

Hm. I have no idea where a cache size limit is set.
This is my ConfigureServices:

Code: Select all

public void ConfigureServices(IServiceCollection services)
{
	services.AddDevExpressControls();

	services.AddEntityFrameworkNpgsql().
		AddDbContext<ApplicationDbContext>(options =>
			options.UseNpgsql(Configuration.GetConnectionString("DefaultConnection"))
		);

    services.AddDatabaseDeveloperPageExceptionFilter();


    services.AddIdentity<ApplicationUser, IdentityRole>(options => 
    { 
        options.SignIn.RequireConfirmedAccount = false;
        options.Password.RequireDigit = false;
        options.Password.RequireLowercase = false;
        options.Password.RequireUppercase = false;
        options.Password.RequireNonAlphanumeric = false;
        options.Password.RequiredUniqueChars = 0;                
    })
        .AddEntityFrameworkStores<ApplicationDbContext>().AddDefaultTokenProviders();


	services.Configure<DataProtectionTokenProviderOptions>(opt => opt.TokenLifespan = TimeSpan.FromDays(7));

	services.AddAuthorization(options =>
    {
        options.FallbackPolicy = new AuthorizationPolicyBuilder()
            .RequireAuthenticatedUser()
            .Build();
    });

	services.AddAuthentication(options =>
	{
		options.DefaultScheme = CookieAuthenticationDefaults.AuthenticationScheme;
	})
	.AddCookie();

	services.AddRazorPages();
	services.ConfigureApplicationCookie(options => { 
		options.LoginPath = "/Accounts/Login";
		options.AccessDeniedPath = "/Home/AccessDenied";
	});

	services.AddControllersWithViews()
		.AddNewtonsoftJson(options =>
		options.SerializerSettings.ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore).AddRazorRuntimeCompilation();

	
	services.ConfigureReportingServices(configurator => {					
		configurator.ConfigureWebDocumentViewer(viewerConfigurator => {
			viewerConfigurator.UseCachedReportSourceBuilder();
		});
	});

	services.AddAutoMapper(typeof(Startup));

	services.AddTransient<DbSeeder>();		
	services.AddHttpClient<ExternalAuthService>();
	services.AddScoped<RolesService>();
	services.AddScoped<ITnoesRepository, TnoesRepository>();
	services.AddSingleton<IScopedDbContextProvider<ApplicationDbContext>, ScopedDbContextProvider<ApplicationDbContext>>();
	services.AddSingleton<OperationsStatusesService>();
	services.AddTransient<IApiKeyValidation, ApiKeyValidation>();
	services.AddScoped<ApiKeyAuthFilter>();
	services.AddScoped<SvodReportService>();			

	services.AddHttpContextAccessor();
}

I experimented a little bit and it seems that adding
services.AddMemoryCache();
at the start of ConfigureServices solved the problem.
