I have a problem with dbcontext.users.dadd

I am making a discord bot and i am writing a function to save jobs but it doesn't get further than var add new jobs..

   public static async Task SaveJobs(string nosaukums, string apraksts, string statuss)
    {
        using (var DBcontext = new SQLiteDBcontext())
        {
            var add = new Jobs
            {
                Apraksts = apraksts,
                Notikums = nosaukums,
                Statuss = statuss,
                Darbinieki = ""
            };

            DBcontext.Jobs.Add(add);
            await DBcontext.SaveChangesAsync();
        }

    }
