Why does a role shows as “not exist” even when present in the database (asp.net mvc)

Question

I\'m trying to add users to a role when registering a user so i seeded the roles and updated the database with the code below in the migrations.cs class

Answer 1

The second parameter is the string role, as in "Reviewer" not the id of the role. It's erroring out because there is literally no role with Name equal to that GUID.
