Hey, we are using:

- Elasticsearch 6.2.3 hosted by [http://cloud.elastic.co](http://cloud.elastic.co)
- Java RestLowLevelClient 6.2.3

**Request with low level client:**

```
	restHighLevelClient.getLowLevelClient().performRequest(
	"POST",
	"INDEX/_delete_by_query?conflicts=proceed",
	Collections.emptyMap(),
	new StringEntity("{\"query\":{\"match_all\":{}}}", APPLICATION_JSON));

```

**Response:**

```
Caused by: org.elasticsearch.client.ResponseException: method [POST], host [HOST], URI [HOST/_delete_by_query], status line [HTTP/1.1 400 BAD_REQUEST]

The requests works fine when i execute with kibana or the RestClient plugin for firefox.  
With the JavaLowLevel Client i could also add and remove an alias. But delete by query does not work.

There are no logs regarding to the delete by query request in elasticsearch.

Any tips? Thanks.

Found the error.  
I had to put a slash "/" before the index. 😅

```
"/INDEX/_delete_by_query?conflicts=proceed"
```
