SCIM - GET all users work, but a specific users does not

Hi,

I’ve encountered inconsistency between /users and /users/{id}.

I have a user that I cannot get its resource using /users/{id}, though I do get it by querying all users using /users.

The exception I get from querying the specific user is:

System.NullReferenceException: Object reference not set to an instance of an object.
  ?, in void SCIMRepresentationExtensions.ApplyEmptyArray(SCIMRepresentation representation)+(SCIMRepresentationAttribute a) => { }
  ?, in bool Enumerable.Any<TSource>(IEnumerable<TSource> source, Func<TSource, bool> predicate)
  ?, in void SCIMRepresentationExtensions.ApplyEmptyArray(SCIMRepresentation representation)
  ?, in async Task<IActionResult> BaseApiController.InternalGet(string id)
  ?, in async ValueTask<IActionResult> TaskOfIActionResultExecutor.Execute(IActionResultTypeMapper mapper, ObjectMethodExecutor executor, object controller, object[] arguments)
  ?, in async Task ControllerActionInvoker.InvokeActionMethodAsync()+Awaited(?)

  ?, in async Task ControllerActionInvoker.InvokeInnerFilterAsync()+Awaited(?)
  ?, in async Task ResourceInvoker.InvokeNextExceptionFilterAsync()+Awaited(?)

Looking at its attributes, I do not see something special. Attached is a CSV with the user’s attributes. single-user-scim-data.csv

Please let me know if this helps or whether more information is needed.

Thanks Dan

I could reproduce your bug on my local machine by using your sample data (single-user-scimdata.csv). In fact, there was an issue in the algorithm used to set the $ref parameter (enrichment).

I’m going to make a release tomorrow.

How did you manage to reproduce this? Do you have a test for this issue?
