• 해결

Room 에 @TypeConverter 을 이용하여 저장 및 불러올때의 문제로 아래 코드로 변경 후 해결

@TypeConverter
fun toByteArray(bitmap : Bitmap) : ByteArray = ByteArrayOutputStream().apply { bitmap.compress(Bitmap.CompressFormat.PNG, 100, this) }.toByteArray()

@TypeConverter
fun toBitmap(bytes : ByteArray) : Bitmap = BitmapFactory.decodeByteArray(bytes, 0, bytes.size)

// @TypeConverter
// fun bitmapToJson(target: Bitmap) = Gson().toJson(target)

// @TypeConverter
// fun jsonToBitmap(target: String) = Gson().fromJson(target, Bitmap::class.java)
