Hi!

I have same issue. I'm using .net core 2.1, maybe this is source of problem, or is it related with exceptions that are throw in EfDiagramsMiddleware.cs?

if (loggerFactory == null)
            {
                throw new ArgumentNullException(nameof(loggerFactory));
            }

if (options == null)
            {
                throw new ArgumentNullException(nameof(options));
            }

I'm using code first method, and this is my forehead of DatabaseContext:

public class DatabaseContext : DbContext
    {
        public DatabaseContext(DbContextOptions<DatabaseContext> options) : base(options) { }

        public DbSet<Client> Clients { get; set; }
