EmbeddedElastic.createIndex method throws NullPointerException

[mallim]

NullPointerException at the following place when calling EmbeddedElastic.createIndex:

this.indicesDescription.getIndexSettings(indexName).ifPresent((indexSettings) -> {
	this.setIndexSettingsAsEntity(request, indexSettings);
});

For reference, I am able to do the following with high level rest client:

CreateIndexRequest request = new CreateIndexRequest("index");
CreateIndexResponse createIndexResponse = restHighLevelClient.indices().create(request);

To be able to do anything with this I will need to see your embedded elasticsearch configuration and full stacktrace

Hello, I have a similar problem.
I use Embedded ES for testing, and I am setting up the ES instance in @Before phase (I call EmbeddedElastic.start()), and for the specific test I try to create an index with EmbeddedElastic.createIndex(String) in the start of @Test phase which returns NPE.

I find this strange, because in athoner @Test I use EmbeddedElastic.index(String,String,String) to create documents and it works fine. Also note, that EmbeddedElastic.Builder.withIndex() also works fine

I insert a reference code to what I mean:

class BasicElasticSearchIndexApiTest {

    private var embeddedES : EmbeddedElastic = EmbeddedElastic.builder()
        .withElasticVersion(ESVersion)
        .withSetting(PopularProperties.CLUSTER_NAME, CLUSTER)
        .withSetting(PopularProperties.TRANSPORT_TCP_PORT, 9350)
        .withIndex(META_INDEX)
        .withStartTimeout(1000, TimeUnit.SECONDS)
        .build()

    @Before
    fun setUp() {
        embeddedES.start().recreateIndex(META_INDEX)
    }

    @Test
    fun `test which works`(context: TestContext){
        embeddedES.index(META_INDEX, META_TYPE, data.encode())
    }

    @Test
    fun `test which returns NPE`(context: TestContext){
        embeddedES.createIndex(TEST_INDEX)
    }

}

This code above is in Kotlin and contains only relevant information regarding this problem.
I also use Vert.x because I run these test asynchronously

The stacktrace was the following:

java.lang.NullPointerException
	at pl.allegro.tech.embeddedelasticsearch.ElasticRestClient.createIndex(ElasticRestClient.java:60)

Thank you for your forward help

Update: I think I have misread the usage and functionality.

If I understood correctly, EmbeddedElastic.createIndex() works only for indices already created during setup. As it is in the docs:

creates index with name specified during EmbeddedElastic creation; note that this index is created during EmbeddedElastic startup, you will need this method only if you deleted your index using deleteIndex method

So @mallim could it be, that the index you are trying to create is not yet created via EmbeddedElastic.builder?
