¿Porque cuando genero reportes en Oracle me da el error ORA-01790?

La aplicación la tengo localmente y la base de datos de ORACLE son las de desarrollo, cuando trató de generar cualquier reporte me muestra el siguiente error:

System.Data.EntityCommandExecutionException: An error occurred while executing the command definition. See the inner exception for details. ---> Oracle.ManagedDataAccess.Client.OracleException: ORA-01790: la expresión debe tener el mismo tipo de dato que la expresión correspondiente at OracleInternal.ServiceObjects.OracleCommandImpl.VerifyExecution(OracleConnectionImpl connectionImpl, Int32& cursorId, Boolean bThrowArrayBindRelatedErrors, OracleException& exceptionForArrayBindDML, Boolean& hasMoreRowsInDB, Boolean bFirstIterationDone) at OracleInternal.ServiceObjects.OracleCommandImpl.ExecuteReader(String commandText, OracleParameterCollection paramColl, CommandType commandType, OracleConnectionImpl connectionImpl, OracleDataReaderImpl& rdrImpl, Int32 longFetchSize, Int32 lobPrefetchSize, OracleDependencyImpl orclDependencyImpl, Int64[] scnForExecution, Int64[]& scnFromExecution, OracleParameterCollection& bindByPositionParamColl, Boolean& bBindParamPresent, Boolean isDescribeOnly, Boolean isFromEF) at Oracle.ManagedDataAccess.Client.OracleCommand.ExecuteReader(Boolean requery, Boolean fillRequest, CommandBehavior behavior) at Oracle.ManagedDataAccess.Client.OracleCommand.ExecuteDbDataReader(CommandBehavior behavior) at System.Data.Common.DbCommand.ExecuteReader(CommandBehavior behavior) at System.Data.EntityClient.EntityCommandDefinition.ExecuteStoreCommands(EntityCommand entityCommand, CommandBehavior behavior) --- End of inner exception stack trace --- at System.Data.EntityClient.EntityCommandDefinition.ExecuteStoreCommands(EntityCommand entityCommand, CommandBehavior behavior) at System.Data.Objects.Internal.ObjectQueryExecutionPlan.Execute[TResultType](ObjectContext context, ObjectParameterCollection parameterValues) at System.Data.Objects.ObjectQuery`1.GetResults(Nullable`1 forMergeOption) at System.Data.Objects.ObjectQuery`1.System.Collections.Generic.IEnumerable<T>.GetEnumerator() at System.Linq.Enumerable.FirstOrDefault[TSource](IEnumerable`1 source) at System.Data.Objects.ELinq.ObjectQueryProvider.<GetElementFunction>b__1[TResult](IEnumerable`1 sequence) at System.Data.Objects.ELinq.ObjectQueryProvider.ExecuteSingle[TResult](IEnumerable`1 query, Expression queryRoot) at System.Data.Objects.ELinq.ObjectQueryProvider.System.Linq.IQueryProvider.Execute[S](Expression expression) at System.Linq.Queryable.FirstOrDefault[TSource](IQueryable`1 source) at Aseinfo.Infrastructure.Base.Entity.EntityServiceBase`2.GetEntityById(IdT id, Expression`1[] includes) in c:\VH4\Infrastructure\Base\Entity\EntityServiceBase.cs:line 261 at Aseinfo.Infrastructure.Controllers.ReportesController.GenerarReporte(String codigoReporte, Dictionary`2 parametros) in c:\VH4\Infrastructure\Controllers\ReportesController.cs:line 188

Lo extraño es que reportes que me funcionaban anteriormente también muestran este mensaje, ¿Que podrá ser?
