现在支持update语句了吗

我刚请求了一下update语句，报错了 { "error": { "root_cause": [ { "type": "null_pointer_exception", "reason": "Cannot invoke "org.elasticsearch.rest.BaseRestHandler$RestChannelConsumer.accept(Object)" because "action" is null" } ], "type": "null_pointer_exception", "reason": "Cannot invoke "org.elasticsearch.rest.BaseRestHandler$RestChannelConsumer.accept(Object)" because "action" is null" }, "status": 500 }
