我对我的ViewModel收到了以下错误：

错误指向我的应用程序中的3个位置。第一个是在我的MainActivity. kt类'onCreate（）方法中启动viewModel对象：

override fun onCreate(savedInstanceState: Bundle?) {
        ...

        viewModel = ViewModelProviders.of(this).get(EntryViewModel::class.java)
        viewModel.allEntries.observe(this, Observer { entries -> adapter.submitList(entries) })

        ...
    }

2ndpoint是我的存储库类中的LiveData对象：

class EntryRepository(application: Application) {
    private val entryDAO: EntryDAO
    lateinit var allEntries: LiveData<List<Entry>>

    ...
    }

第3点是ViewModel中的存储库对象：

class EntryViewModel(application: Application) : AndroidViewModel(application) {
    private val repository: EntryRepository = EntryRepository(application)
    val allEntries: LiveData<List<Entry>>

    init {allEntries = repository.allEntries }

    fun insert(entry: Entry) {repository.insert(entry)}

    fun update(entry: Entry) {repository.update(entry)}

    fun delete(entry: Entry) {repository.update(entry)}

    fun deleteAll() {repository.deleteAllEntries()}
}

第一次出现此错误时，我在S/O上被告知，这是由于我的gradle文件中的一些实现与AnroidX不兼容。修复后，问题仍然存在。
