Error al hacer que Enum sea la key principal en la biblioteca de la database de la sala

Estoy usando una enumeración para ser una key principal para la biblioteca de database Room con TypeConvertor y no comstack en time de ejecución y arroja un error

Aquí está mi convertidor

• ¿Cómo unir dos tablas en Android usando el método de consulta del proveedor de contenido?
• Base de datos de android de Kotlin: no se puede convertir java.lang.String en android.database.Cursor
• No se puede acceder a BaseColumns proporciona la propiedad _ID en Kotlin
• Android (Kotlin): sobrescribe el nombre para la input del logging de llamadas
• IlegalStateException donde se lanzó, al intentar recuperar los valores de la instancia de RoomDatabase

class QuranIndexConverter { @TypeConverter fun toQuranIndex(index: String): QuranIndex { return QuranIndex.valueOf(index) } @TypeConverter fun toStringIndex(quranIndex: QuranIndex): String { return quranIndex.name }} 

Aquí el Dao

  @Dao interface SuraDao { @Query("SELECT * FROM " + Constants.TABLE_NAME) fun getAll(): LiveData<List<Sura>> @Insert fun insertAll(suras: List<Sura>) @Insert fun insert(sura: Sura) @Delete fun deleteAll(suras: List<Sura>) @Delete fun delete(sura: Sura)} 

Aquí está el module

 @Entity(tableName = Constants.TABLE_NAME) data class Sura( @PrimaryKey val quranIndex: QuranIndex = QuranIndex.ABS, @ColumnInfo(name = "sura_name") val suraName: String = "Abasa", @ColumnInfo(name = "download_url") val downloadUrl: String = "www.google.com") 

Aquí está la database de la habitación

 @Database( entities = arrayOf(Sura::class), version = 1) @TypeConverters(QuranIndexConverter::class) abstract class Appdatabase : RoomDatabase() { abstract fun suraDao(): SuraDao }
