Service is not register in Eureka because of Autofac #1394

Closed xXAvoraXx closed 9 months ago

xXAvoraXx commented 9 months ago

Describe the bug

I am trying to register my .net 7 web api application to eureka server, but I am getting the following error, why?

Code Explain

I use Autofac for service registrations, I make autofac configurations in a separate dotnet 7 library project. Even though I wrote the necessary configurations to connect to the Eureka service, I get an error.

Codes: CoreModule 

    using Project.Services.Core.Extensions;
    using Project.Services.Core.Utilities.IoC;
    using Microsoft.Extensions.DependencyInjection;
    using StackExchange.Redis;
    using System.Diagnostics;
    using Serilog;
    using Microsoft.Extensions.Configuration;
    using Steeltoe.Discovery.Client;
    using Steeltoe.Discovery.Eureka;

    namespace Project.Services.Core.DependencyResolvers
    {
        public class CoreModule : ICoreModule
        {
            public void Load(IServiceCollection services, IConfiguration configuration)
            {
                services.AddServiceDiscovery(o => o.UseEureka());

                services.AddMemoryCache();
                services.AddSingleton<ICacheManager, MemoryCacheManager>();
                services.AddSingleton<IDistributedCacheManager, DistributedCacheManager>();
                services.AddHttpContextAccessor();
                services.AddSingleton<Stopwatch>();

            }
        }
    }

Program.cs

    builder.Services.AddDependencyResolvers(new ICoreModule[]
                {
                    new CoreModule()
                }, builder.Configuration);

appsettings.json config

      "Spring": {
        "Application": {
          "Name": "STOCK-SERVICE"
        }
      },
      "Eureka": {
        "Client": {
          "ServiceUrl": "http://localhost:867/eureka/",
          "ValidateCertificates": false,
          "ShouldRegisterWithEureka": true
        },

        // No docke instance added
        "Instance": {
          //"port": 5004,
          "NonSecurePort": 5004,
          "HostName": "localhost",
          "InstanceId": "Stock.API,Port:5004",
          "StatusPageUrlPath": "/swagger/index.html"
          //"HealthCheckUrlPath": "/api/values/healthcheck"
        }
      }

It gives an error when run with docker-compose, but no error occurs when run with IIS.

This is going to be an error with your app code, not a bug with Autofac. You already asked this on Stack Overflow so hopefully someone in the community can answer.

You'll notice I asked you for the inner exception over on Stack Overflow. Not just the message, the whole stack trace. That stack trace is good to tell you what code you should be looking at, as explained in our troubleshooting docs. From the message here, seems like you have a null reference. That's the error.

I wish we had the bandwidth to give away free consulting hours and debug everyone's app code but we don't, so Stack Overflow is your best avenue. Hopefully someone in the community has that kind of time to allocate.
