android kotlin room Kotlin

I recently switched to I've been researching this but I'm experiencing an unexpected behavior when trying to perform transactions with Room Database in my Android 14 app using Kotlin coroutines... I have a function that should insert a list of items into the database, but sometimes it fails silently without throwing any exceptions, and the data doesn't get saved. Here is the relevant code snippet: ```kotlin @Transaction suspend fun insertItems(items: List<Item>) { itemDao.insertAll(items) } viewModelScope.launch { try { insertItems(itemList) } catch (e: Exception) { Log.e("DB_ERROR", "Failed to insert items: ${e.message}") } } ``` I verified that the `itemList` contains valid data before calling `insertItems`. Additionally, I have enabled `Room`'s logging to see what is happening under the hood, but there are no logs indicating any issues during the insertion process. One thing I noticed is that if I call the insert function directly without wrapping it in a transaction, the data is saved correctly. My understanding was that using `@Transaction` should ensure that the operations are atomic and handled as expected. Is there a potential scenario with how Room handles transactions in conjunction with coroutines on Android 14? I also tried different scopes for launching the coroutine but faced the same scenario. Any guidance on this or similar experiences would be appreciated! My `build.gradle` dependencies include: ```gradle def room_version = "2.5.0" implementation "androidx.room:room-runtime:$room_version" kapt "androidx.room:room-compiler:$room_version" implementation "androidx.room:room-ktx:$room_version" ``` Let me know if I missed any details or if you need additional information. I'm working on a API that needs to handle this. What's the best practice here? I'm developing on Ubuntu 20.04 with Kotlin. I'm open to any suggestions. I'd be grateful for any help.
