Problem description

Delete-by-query cannot be used because result cannot be parsed. Fails with

co.elastic.clients.util.MissingRequiredPropertyException: Missing required property 'DeleteByQueryResponse.throttledMillis'
	at co.elastic.clients.util.ApiTypeHelper.requireNonNull(ApiTypeHelper.java:76)
	at co.elastic.clients.elasticsearch.core.DeleteByQueryResponse.<init>(DeleteByQueryResponse.java:118)

	at co.elastic.clients.elasticsearch.ElasticsearchClient.deleteByQuery(ElasticsearchClient.java:568)

Property throttledUntilMillis in the same object is apparently also affected.

Please note that even the workaround switch ApiTypeHelper.DANGEROUS_disableRequiredPropertiesCheck(true) does not help here, since the field is defined as primitive long. Using it results in

java.lang.NullPointerException: Cannot invoke "java.lang.Long.longValue()" because the return value of "co.elastic.clients.util.ApiTypeHelper.requireNonNull(Object, Object, String)" is null
