[main]TasksRepository.refreshTasks() might throw an exception
The possible exception in DefaultTasksRepository.updateTasksFromRemoteDataSource() is not handled in either repository level or in the VM's that are calling refreshTasks() inside viewModelScope.launch
To resolve the issue in TasksRepository.refreshTasks() potentially throwing an unhandled exception, you should wrap the call in a try-catch block, either:
Directly inside the refreshTasks() method of the repository, or
In each ViewModel that calls it via viewModelScope.launch { ... }.
Recommended Fix – Handle Exception in Repository Layer Update DefaultTasksRepository.updateTasksFromRemoteDataSource() to handle exceptions internally:
suspend fun refreshTasks() { try { updateTasksFromRemoteDataSource() } catch (e: Exception) { Log.e("TasksRepository", "Error refreshing tasks", e) // Optional: you can emit an error state or rethrow a custom exception if needed } } Alternatively – Handle in the ViewModel If you prefer leaving the repository clean and want handling per consumer:
viewModelScope.launch { try { tasksRepository.refreshTasks() } catch (e: Exception) { _uiState.value = UiState.Error("Unable to refresh tasks: ${e.message}") Log.e("TasksViewModel", "Failed to refresh tasks", e) } } Optional Improvements Define a custom exception like RemoteDataFetchException to make error states more specific.
Update UI state to reflect errors for better user feedback.
Use a Result wrapper or sealed class (e.g., Success, Error, Loading) for more robust flow handling.
Summary To fix this issue:
Wrap updateTasksFromRemoteDataSource() in a try-catch.
Log or propagate the exception as needed.
Optionally, communicate failure to the UI via UiState.
