I get these errors when running @test on my database:

My test:

@RunWith(AndroidJUnit4.class)
public class GameQuestionDaoTest {

    @Rule
    public InstantTaskExecutorRule instantTaskExecutorRule = new InstantTaskExecutorRule();

    private GameDatabase gameDatabase;
    private GameDao gameDao;
    private QuestionDao questionDao;

    @Before
    public void setUp() throws Exception {
        Context context = ApplicationProvider.getApplicationContext();
        gameDatabase = Room.inMemoryDatabaseBuilder(context, GameDatabase.class)
                .allowMainThreadQueries()
                .build();
        gameDao = gameDatabase.gameDao();
        questionDao = gameDatabase.questionDao();
    }

    @After
    public void closeDb() throws IOException {
        gameDatabase.close();
    }

    @Test
    public void storeAndGet() {
        Game game = new Game("cat","diff");
        int id = (int) gameDao.insertReturnId(game);
        for(int i=0;i<5;i++){
            Question question = new Question("1", "2", "3", "4", "5");
            question.setId(id);
            questionDao.insert(question).blockingAwait();
        }
        int a = questionDao.getAll().blockingGet().size();
        assertEquals(4, a);
    }
}

My entities:

@Entity(tableName = "games")
public class Game {

    @PrimaryKey(autoGenerate = true)
    @ColumnInfo(name = "id")
    private int gameId;
}

and

@Entity(foreignKeys = @ForeignKey(entity = Game.class,
        parentColumns = "id",childColumns = "question_id",
        onDelete = ForeignKey.CASCADE),
        tableName = "questions")
public class Question {

    @PrimaryKey(autoGenerate = true)
    @ColumnInfo(name = "id")
    private int id;
}

Looked at similar questions on Stackoverflow but have not managed to find anything that can help my case. Any suggestions?
