Updating/deleting a resource as part of a bulk request throws exception

[canea-asb]

Reproduction steps

1. Send a request with the following body to /Bulk, which creates two users:

{
    "schemas": ["urn:ietf:params:scim:api:messages:2.0:BulkRequest"],
    "Operations": [{
        "method": "POST",
        "path": "/Users",
        "bulkId": "user15",
        "data": {
            "schemas": [
                "urn:ietf:params:scim:schemas:core:2.0:User",
                "urn:ietf:params:scim:schemas:extension:enterprise:2.0:User"
            ],
            "externalId": "O9876",
            "userName": "[email protected]",
            "name": {
                "givenName": "Olivia",
                "familyName": "Johnson"
            },
            "active": "true",
            "urn:ietf:params:scim:schemas:extension:enterprise:2.0:User": {
                "department": "Marketing"
            }
        }
    },
    {
        "method": "POST",
        "path": "/Users",
        "bulkId": "user16",
        "data": {
            "schemas": [
                "urn:ietf:params:scim:schemas:core:2.0:User",
                "urn:ietf:params:scim:schemas:extension:enterprise:2.0:User"
            ],
            "externalId": "P1234",
            "userName": "[email protected]",
            "name": {
                "givenName": "Peter",
                "familyName": "Smith"
            },
            "active": "false",
            "urn:ietf:params:scim:schemas:extension:enterprise:2.0:User": {
                "department": "Procurement"
            }
        }
    }]
}

2. Send a request with the following body to /Bulk, which updates two users:
   Note that you need to replace "[insert user id here]" with the IDs of the users created in step 1.

{
    "schemas": ["urn:ietf:params:scim:api:messages:2.0:BulkRequest"],
    "Operations": [{
        "method": "PUT",
        "path": "/Users/[insert user id here]",
        "bulkId": "user15",
        "data": {
            "schemas": [
                "urn:ietf:params:scim:schemas:core:2.0:User",
                "urn:ietf:params:scim:schemas:extension:enterprise:2.0:User"
            ],
            "externalId": "O9876",
            "userName": "[email protected]",
            "name": {
                "givenName": "Olivia",
                "familyName": "Swanson"
            },
            "active": "false",
            "urn:ietf:params:scim:schemas:extension:enterprise:2.0:User": {
                "department": "Marketing"
            }
        }
    },
    {
        "method": "PUT",
        "path": "/Users/[insert user id here]",
        "bulkId": "user16",
        "data": {
            "schemas": [
                "urn:ietf:params:scim:schemas:core:2.0:User",
                "urn:ietf:params:scim:schemas:extension:enterprise:2.0:User"
            ],
            "externalId": "P1234",
            "userName": "[email protected]",
            "name": {
                "givenName": "Peter",
                "familyName": "Green"
            },
            "active": "true",
            "urn:ietf:params:scim:schemas:extension:enterprise:2.0:User": {
                "department": "Procurement"
            }
        }
    }]
}

Expected outcome
The users were updated according to the second bulk request.

Actual outcome
The following exception is thrown:

fail: SimpleIdServer.Scim.Api.UsersController[0]
      resource  not found
      SimpleIdServer.Scim.Exceptions.SCIMNotFoundException: resource  not found
         at SimpleIdServer.Scim.Commands.Handlers.ReplaceRepresentationCommandHandler.Validate(ReplaceRepresentationCommand replaceRepresentationCommand)
         at SimpleIdServer.Scim.Commands.Handlers.ReplaceRepresentationCommandHandler.Handle(ReplaceRepresentationCommand replaceRepresentationCommand)
         at SimpleIdServer.Scim.Api.BaseApiController.InternalUpdate(String prefix, String id, RepresentationParameter representationParameter, CancellationToken cancellationToken)

Also, the SCIM server returns the following response:

{
    "schemas": [
        "urn:ietf:params:scim:api:messages:2.0:BulkResponse"
    ],
    "Operations": [
        {
            "method": "PUT",
            "bulkId": "user15",
            "status": {
                "code": 404,
                "response": {}
            }
        },
        {
            "method": "PUT",
            "bulkId": "user16",
            "status": {
                "code": 404,
                "response": {}
            }
        }
    ]
}

Note!
An example project is attached to this issue that can be used to start the SCIM server that was used in the bug reproduction steps.

"Hello,

Indeed, there is an error in the implementation 😔.
For some reason, even though the id parameter is passed into the sub HTTP request, this value is not correctly transmitted by the route to the action.
I have made some modifications in the project to fix this issue!
