es6升级到7后报错illegal_argument_exception

请求内容如下，在es6可以执行成功，7报错"caused_by": { "type": "illegal_argument_exception", "reason": "Illegal list shortcut value [values]." }

{
	"query": {
		"bool": {
			"must": [{
				"range": {
					"appoint_time": {
						"gte": "2022-07-05 03:00:00"
					}
				}
			}, {
				"range": {
					"appoint_time": {
						"lte": "2022-07-06 03:00:00"
					}
				}
			}, {
				"term": {
					"line_id": "361000_to_362400"
				}
			}]
		}
	},
	"from": 0,
	"size": 0,
	"aggs": {
		"aggs_res": {
			"terms": {
				"field": "order_status"
			},
			"aggs": {
				"group": {
					"terms": {
						"script": "doc['order_status'].values",
						"size": 5000
					},
					"aggs": {
						"pcount": {
							"sum": {
								"field": "pcount"
							}
						}
					}
				}
			}
		}
	}
}

这里将"script": "doc['order_status'].values"的values改为value即可成功返回，但是目前还没有在官方文档中找到对应的更新说明
