"Lateinit property `app` has not been initialized" Error after Hilt Migration

By -

I'm migrating our codebase from Dagger 2 to Hilt. I'm kind of a noob. I've gotten everything to build and compile. There is a crasher on app launch with this error:

The property app in BaseApplication is referenced all over the codebase.

BaseApplication.kt

@HiltAndroidApp
open class BaseApplication : Application() {
    ....

    // (Injections in case they are relevant) //

    @Inject
    lateinit var hsAnalytics: HsAnalytics

    ....

    @Inject @field:Named(NetworkService.Keys.GRAPH_QL_OKHTTP_CLIENT)
    lateinit var okHttpClient: OkHttpClient

    @Inject
    lateinit var apolloClient: ApolloClient
    ....
    
    // onCreate()
    override fun onCreate() {
        super.onCreate()

        // Assign static "app" variable before ANYTHING else. <- This note was in the code base from an old dev that is no longer around
        app = this
    
        ....
    }

        ....
    companion object {
        ....
        // TODO: Should consider whether or not these should be static <- Notes from old dev who isn't around anymore
        //<editor-fold desc="Utility methods to help non-context classes retrieve context-related objects">
        @JvmStatic
        lateinit var app: BaseApplication
            private set
        ....
    }
}

AppModule.kt

@Module
@InstallIn(SingletonComponent::class)
object AppModule {

    @Singleton
    @Provides
    fun provideApplication(@ApplicationContext application: BaseApplication): BaseApplication {
        return application as BaseApplication
    }

    @Provides
    @Singleton
    internal fun provideContext(application: BaseApplication): Context = application
}

Any idea why app suddenly isn't being instantiated?

Hibernate Search - Elasticsearch with JSON manipulation

By -
Elasticsearch with JSON manipulation Elasticsearch ships with many features. It is possible that at some point, one feature you need will not be exposed by the Search DSL. To work around such limitations, Hibernate Search provides ways to: Transform the HTTP request sent to Elasticsearch for search queries. Read the raw JSON of the HTTP response received from Elasticsearch for search queries. Direct changes to the HTTP request may conflict with Hibernate Search features and be supported differently by different versions of Elasticsearch. Similarly, the content of the HTTP response may change depending on the version of Elasticsearch, depending on which Hibernate Search features are used, and even depending on how Hibernate Search features are implemented. Thus, features relying on direct access to HTTP requests or responses cannot be guaranteed to continue to work when upgrading Hibernate Search, even for micro upgrades (x.y.z to x.y.(z+1)). Use this at your own risk.

Spring Elasticsearch Operations

By -
Elasticsearch Operations Spring Data Elasticsearch uses two interfaces to define the operations that can be called against an Elasticsearch index. These are ElasticsearchOperations and ReactiveElasticsearchOperations. Whereas the first is used with the classic synchronous implementations, the second one uses reactive infrastructure. The default implementations of the interfaces offer: Read/Write mapping support for domain types. A rich query and criteria api. Resource management and Exception translation. ElasticsearchTemplate The ElasticsearchTemplate is an implementation of the ElasticsearchOperations interface using the Transport Client. @Configuration public class TransportClientConfig extends ElasticsearchConfigurationSupport {   @Bean   public Client elasticsearchClient() throws UnknownHostException {                      Settings settings = Settings.builder().put("cluster.name", "elasticsearch").build();     TransportClient client = new P
