Como rastrear o motivo de um erro em um add-migration?

Eu estou fazendo um add-migration com mappings para as entidades, porém está dando um erro e não sei onde ver o motivo do erro. using System; #nullable disable namespace TCM.RH.Data.Migrations { /// public partial class CriacaoBDTCMSistemaRHVotacao : Migration { /// protected override void Up(MigrationBuilder migrationBuilder) { migrationBuilder.CreateTable( name: "TLotacaoVotacao", columns: table => new { idLotacaoVotacao = table.Column(type: "int", nullable: false) .Annotation("SqlServer:Identity", "1, 1"), codLotacao = table.Column(type: "nvarchar(64)", nullable: false), idLotaocaoVotacaoVotacao = table.Column(type: "int", nullable: false), lotacao = table.Column(type: "nvarchar(80)", maxLength: 80, nullable: false) }, constraints: table => { table.PrimaryKey("PK_LotacaoVotacao", x => x.idLotacaoVotacao); });
