Комната - Не уверен, как преобразовать курсор в тип возврата этого метода (java.lang.object) ⇐ Android

[Anonymous]

Я создаю проект с комнатой, и у меня есть следующие коды: < /p>
Для моего класса сущности: < /p>

Код: Выделить всё

import androidx.room.ColumnInfo

для моего класса DAO: < /p>
@Dao

@Insert(onConflict = OnConflictStrategy.REPLACE)
suspend fun insert(matchEntity: MatchEntity): Long

@Update
suspend fun update(matchEntity: MatchEntity): Int

@Delete
suspend fun delete(matchEntity: MatchEntity)

@Query("SELECT * FROM matches")
suspend fun getAll(): List

@Query("SELECT * FROM matches WHERE id = :id")
suspend fun getById(id: Int): List
}

Я работал с комнатой много раз, но на этот раз я получаю эту ошибку: < /p>

C:\Users\Leona\workspace\wingman\app\build\tmp\kapt3\stubs\debug\com\hikarisource\wingman\data\local\dao\MatchDao.java:28: error: Query method parameters should either be a type that can be converted into a database column or a List / Array that contains such type. You can consider adding a Type Adapter for this.
