[Solved] Illegal State - START_ARRAY

[Lee_Gee]

Running the latest ES and Node.js client, the below query produces an error "illegal_state_exception", "Can't get text on a START_ARRAY at 1:80", although the query seems to conform to the docs:

https://www.elastic.co/guide/en/elasticsearch/guide/current/bool-query.html

                    }
                },
                {

Working for me on 5.0 GA release:

DELETE test
POST test/doc
{
	"type":"posting",
	"userid":10158245646690355,
	"text":"xx xxxxxxxxxxxxx"

}
GET test/doc/_search
{
	"query": {
		"bool": {
			"must": [
				{
					"match": {
						"type": "posting"
					}
				},
				{
					"match": {
						"userid": "10158245646690355"
					}
				}
			],
			"should": [
				{
					"match_phrase": {
						"text": "xxx"
					}
				},
				{
					"match_phrase": {
						"text": "xxxxxxxxxxxxx"
					}
				}
			]
		}
	},
	"highlight": {
		"fields": {
			"text": {

				"number_of_fragments": 3

		}
	},

Thank you for trying — it was my error: my JS was logging the wrong query: when I put a 'catch' clause in the right place, I saw I was passing an array where I ought to have been passing a string.
