Неизвестная ошибка SQLiteException (код 0): невозможно преобразовать BLOB в строку при попытке получить данные в ListView

Question

В моем проекте, когда я пытаюсь установить адаптер для ListView из базы данных SQLite, которая содержит изображение в качестве значения BLOB-объекта, я получаю это исключение

Я проверял базу данных при каждом сохранении объекта, он успешно сохраняется в базе данных и находится там прямо сейчас.

Вот мой код базы данных:

public boolean setWorkout(String title,String desc,byte[] img)
    {
        SQLiteDatabase db = this.getWritableDatabase();
        ContentValues cv = new ContentValues();
        cv.put(S_COL_TITLE,title);
        cv.put(S_COL_DESCRIPTION,desc);
        cv.put(S_COL_IMAGES,img);
        long res = db.insert(TABLE_WORKOUT,null,cv);
        if(res==-1)
            return false;
        else
            return true;

    }
    public Cursor getWorkout()
    {
        SQLiteDatabase db = this.getWritableDatabase();
        Cursor data = db.rawQuery("SELECT * FROM "+TABLE_WORKOUT,null);
        return data;
    }

Вот код, где возникает эта проблема:

public class WorkoutFragment extends Fragment{
    String[] fromColumns = {"title", "description","images"};
    int[] toViews = {R.id.ename,R.id.descr,R.id.pic};
    DatabaseHelper db;
    Cursor data;
    SimpleCursorAdapter adapter;
    ListView list;
    public View onCreateView(@NonNull LayoutInflater inflater,
                             ViewGroup container, Bundle savedInstanceState) {
        View root = inflater.inflate(R.layout.fragment_workout, container, false);

        list = root.findViewById(R.id.workout_list);
        db = new DatabaseHelper(getActivity().getApplicationContext());
        data = db.getWorkout();
        adapter = new SimpleCursorAdapter(getActivity().getApplicationContext(), R.layout.workout_list, data, fromColumns, toViews, 0);
        list.setAdapter(adapter);

        Button add = root.findViewById(R.id.fwinsert);
        add.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Intent i = new Intent(getActivity().getApplicationContext(), AddWorkout.class);
                startActivity(i);
            }
        });

        return root;
    }
}
