'Autofac Dependency Resolution Exception with .Net Core

I am trying to hit an endpoint in the WebAPI which is developed using .Net core. I am getting the below error ->

ERROR: API exception occurred

I have already checked that the dependency is resolved properly inside the solution. What else can it be? Also the issue seems to be intermittent and API starts working normally for some time and again starts failing automatically. We have also observed that there is memory spike in the system when we call the API.

Solution 1:[1]

In these cases, it's important to read the whole exception message all the way to the end. It looks like something going on in your code. Truncated:

...Autofac.Core.DependencyResolutionException: An exception was thrown while activating TRS.Flint.BLL.Entities.SessionScope. ---> Autofac.Core.DependencyResolutionException: An exception was thrown while invoking the constructor 'Void .ctor(System.String, System.Transactions.TransactionScopeOption)' on type 'SessionScope'. ---> System.InvalidOperationException: ValueFactory attempted to access the Value property of this instance.
   at System.Lazy`1.CreateValue()
   at System.Lazy`1.LazyInitValue()
   at U4.StudentManagement.Api.Platform.Mvc.Core.Security.IdentityPrincipalProvider.ProvidePrincipalFromHttpContext(HttpContext context) in E:\TC\work\8927d1b2781d569f\Api\Platform\Api.Platform.Mvc.Core\Security\IdentityPrincipalProvider.cs:line 39
   at U4.StudentManagement.Api.Platform.Mvc.Core.Security.HttpContextPrincipalProvider.ProvidePrincipal() in E:\TC\work\8927d1b2781d569f\Api\Platform\Api.Platform.Mvc.Core\Security\HttpContextPrincipalProvider.cs:line 46

So, while trying to create a TRS.Flint.BLL.Entities.SessionScope, it appears to be calling the HttpContextPrincipalProvider.ProvidePrincipal() method. In there it calls IdentityPrincipalProvider.ProvidePrincipalFromHttpContext(), which then looks like it's getting something from a Lazy<T>. But it looks like something in that Lazy<T> may be trying to get the value of itself before it's instantiated? Or something? Whatever it is, it's happening in that Lazy<T> instance, and that's the message:

System.InvalidOperationException: ValueFactory attempted to access the Value property of this instance.

You need to look at your code to see what's going on there.

I do see it has something to do with HttpContext; sometimes folks forget that things may be resolved/called when there is no HttpContext (like at app startup or in a background task) and that causes problems. I don't know if that's the issue here, just suggesting something to look at.

However, otherwise, the exception message and stack trace points you right to the thing in your code to look at. That's where I'd start.
