Elasticsearch Error building the query by Siddhi himself

[Antonio Moreno Borras]

I have installed the Elasticsearch extension and when Siddhi connects and tries to do a query to retrieve information from an Elasticsearch index, this error occurs when Siddhi itself builds the query to Elastic:

Suppressed: org.elasticsearch.client.ResponseException: method [POST], host [http://192.168.168.88:9200], URI [/financial_fraud/_search?typed_keys=true&ignore_unavailable=false&expand_wildcards=open&allow_no_indices=true&search_type=query_then_fetch&batched_reduce_size=512&ccs_minimize_roundtrips=true], status line [HTTP/1.1 400 Bad Request]

It was Siddhi itself who creates the query.
