Error: "Cannot find the services container for route" when using MapVersionedODataRoute

[aniliht]

Hello, I'm using the ASP.NET Core 2.2 and OData. I'm using the following setup in which I create the EdmModel dynamically by looking at the user's claims. Based on the claims, I add a EntitySet A or EntitySet B for example.

When I browse to the controller for EntitySet A and the user doesn't have the claim for it,
I get the following exception when I use the MapVersionedODataRoute. I don't get the exception if I use the OData routebuilder method MapODataServiceRoute(...); which returns 404 as expected instead.

Perhaps my setup is not supported or I misconfigured something? Thanks for your time.

Exception Message:

System.InvalidOperationException: 'Cannot find the services container for route 'odataV1-Unversioned'. This should not happen and represents a bug.'

Apologies for the delayed response. This type of configuration will not work with API Versioning and OData. You cannot use the default OData routing conventions. API Versioning has to replace or extend the default routing conventions to make things work. There are, however, hooks to extend or add additional routing conventions via a callback in the route registration. You don't appear to need this, so I would just remove it. Based on the configuration you've shared, it appears that if you remove that, the rest of it should work.

I hope that helps.

Hello commonsensesoftware,

Thanks for your support! Can you specify which section you propose that I remove from the above configuration?

[commonsensesoftware]

Should definitely remove this:

containerBuilder.AddService<IEnumerable<IODataRoutingConvention>>(
  Microsoft.OData.ServiceLifetime.Singleton,
  sp => ODataRoutingConventions.CreateDefaultWithAttributeRouting(routeName, routeBuilder));

Start with that and if it still doesn't work, we can move on to what else needs to change.

[aniliht]

OK, with those lines removed, it looks like the behavior is the same. I can still reach routes/EntitySets that are in the EdmModel. But when I try to browse to a non-existent route/EntitySet I get the exception from above: "Cannot find the services container for route 'odataV1-Unversioned'. This should not happen and represents a bug."

Seems like any bogus route will cause that exception. For example:
https://localhost:44395/ssss?api-version=1.0

[aniliht]

I can try to build a reproducing sample project without my company's specifics if you think that would help.

[commonsensesoftware]

Repros are always helpful. The simpler the better.

[aniliht]

Here is a simplified repro. There are 2 launch settings.

1. "IIS Express: Bug Repro" - launches a route that doesn't exist and causes the above exception.
2. "IIS Express: Route 'Persons'" - launches a valid route with an entity set that does exist.

Thank you for your time looking into this. Best Regards.

@commonsensesoftware I am getting this same error as well and I have no idea what I am doing wrong or what the exception means. I wrote a detailed Stack Overflow question on it so I will delegate to that here:

I am trying to setup a new .NET Core 3.1 API with OData.

I have a working .NET Core API in 2.2 with OData, so I am going off of that one.

I am using three OData specific nuget packages: Microsoft.AspNetCore.OData v7.3.0, Microsoft.AspNetCore.OData.Versioning v4.1.1 and Microsoft.AspNetCore.OData.Versioning.ApiExplorer v4.1.1.

I keep getting the following response when I send a GET request to my controller:

System.InvalidOperationException: Cannot find the services container for route 'odata-Unversioned'. This should not happen and represents a bug.

Note I have the requirement that the API needs to be versioned. I am not sure if versioning has something to do with this error, but the old .NET Core 2.2 API that I have uses OData versioning as well. Does anyone know what the services container is for a route?

I setup my project similar to https://devblogs.microsoft.com/odata/experimenting-with-odata-in-asp-net-core-3-1/.
I also even tried setting it up exactly as is done in the blog post, however I could not even get OData to work without versioning. When I tried removing versioning, I kept getting a 404 and it couldn't hit the route. Is my routing setup correctly?

Here is the ConfigureServices

public void ConfigureServices(IServiceCollection services)
{
    // Add API versioning
    services.AddApiVersioning(options => options.ReportApiVersions = true);

    // Add OData
    services.AddOData().EnableApiVersioning();
    services.AddODataApiExplorer(options =>
    {
        options.GroupNameFormat = "'v'VVV";
        options.SubstituteApiVersionInUrl = true;
    });

    // Add support for controllers and API-related features
    services.AddControllers(mvcOptions => mvcOptions.EnableEndpointRouting = false);
}

Here is the Configure

// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
    if (env.IsDevelopment())
    {
        app.UseDeveloperExceptionPage();
    }

    app.UseHttpsRedirection();
    app.UseRouting();
    app.UseAuthorization();

    var apiVersion = new ApiVersion(1, 0);
    app.UseMvc(routeBuilder =>
    {
        routeBuilder.Count().Filter().OrderBy().Expand().Select().MaxTop(null);
        app.UseMvc(routes =>
            routes.MapVersionedODataRoute("odata", "api/v{version:apiVersion}", app.GetEdmModel(), apiVersion));
    });
}

Here is the extension method GetEdmModel() I am using above

public static class ODataExtensions
{
    public static IEdmModel GetEdmModel(this IApplicationBuilder app)
    {
        var model = GetEdmModel(app.ApplicationServices);
        return model;
    }

    private static IEdmModel GetEdmModel(IServiceProvider serviceProvider)
    {
        var builder = new ODataConventionModelBuilder(serviceProvider);

        // Entities
        builder.EntityType<Object>().HasKey(x => x.Id);

        // Controllers
        builder.EntitySet<Object>("Object");

        return builder.GetEdmModel();
    }
}

Here is the controller

[Route("odata")]
[ApiVersion("1")] 
public class can : ODataController
{
    private readonly ILogicService _logicService;

    public AlternateIdsController(ILogicService logicService)
    {
        _logicService = logicService;
    }

    [HttpGet]
    [EnableQuery]
    public IActionResult Get()
    {
        return Ok(_logicService.Browse());
    }
}

[commonsensesoftware]

@nfgallimore it doesn't look like the OData mappings match any supported configuration. Your EDM has a MyObject entity set, but that's not the controller you've shown (and I would have expected it to be MyObjects). The AlternateIdsController isn't for an entity set nor seems to provide any unbound functions or actions. Finally, you can thank the OData team for continuing to have their own attributes which are completely different in meaning and use from the standard routing attributes. You need to use [ODataRoutePrefix] and [ODataRoute] respectively. It's fine to use [HttpGet], but OData doesn't really care about it. I suspect with those few changes, you should make some progress.

The Swagger/OpenAPI example here for OData has a number of different scenarios covered, including:

• Routing with attributes
• Routing by convention
• Entity sets
• Unbound functions
• Bound functions
• Bound actions
• Containment
• Entity references

Start with that and then we can move on to other potential issues.
