MVC5: UserManager.AddToRole(): "Error Adding User to Role: UserId not found"?

asp.net-identity asp.net-mvc-5 c# ef-migrations entity-framework-6

Question

I have been experimenting with MVC5/EF6 and trying out the new Identity Authentication with Code-First Migrations. Everything in the solution is currently building and I can add a Migration, but when I perform an update-database through the package manager console in VS2013, my Configuration.cs file fails to fully process my test data into my Tables and outputs Error Adding User to Role: UserId not found.

I have tried explicitly setting a User ID and leaving it to be generated by the Manager (as seen in some examples), but each time I receive the same error message. I know the error is failing in my #region User & User Roles of my Configuration.cs file, but I'm not sure why:

            }
            #endregion

    }
}

Can anyone offer some insight here with what I may be overlooking? For full details, my current catch statment is outputting the following:

Error Adding User to Role: UserId not found.
System.Collections.ListDictionaryInternal

Name: Admin User
Email: Admin@abc.com
user.ID: 1
u.Id: 1
Role: Root
CodeHit: True

When I comment out the explicit Id = "1", for my Admin User, the user.ID and u.Id becomes: ab753316-3d7b-4f98-a13a-d19f7c926976. I had thought it might be my helper methods of GetTestUsers() or GetUserRoles(u.Email) which were the issue, but between my try/catch and the codeHit boolean variable I am using, I have verified the issue is definitely coming from manager.AddToRole(user.Id, role).

I am leaving this here for anyone that might have had a similar issue. I had exactly the same "symptoms". It turns out that the problem related to the password being stored not adhering to the configured password policy (at least one uppercase char, one lowercase char, etc etc).

As per below comments and answers, in general, the same vague error message is thrown when any of the user creation constraints or policies are not followed.

This might include the following:

  • Password policy not followed (this seems to be the most common cause)
  • Required fields being passed through as empty strings / null
  • Duplicate username or email

There is really a wide range of issues which can cause this error to occur. If the above does not solve your problem, I suggest the following:

  1. Familiarize yourself with the rules and policies for identityprovider as it was set up for your solution
  2. As per @Ted's answer below, trace or put a breakpoint on the UserManager.Create method to view the result, as this will likely reveal the cause of your problem.
