Hi, I am trying to send data from Node-RED to Elasticsearch, but I receive the following error: Elasticsearch ERROR: 2018-07-17T14:30:15Z Error: Request error, retrying HEAD [http://localhost/twitterr/tweets/1](http://localhost/twitterr/tweets/1) =\> connect ECONNREFUSED 127.0.0.1:80 at Log.error (/home/workdb/.node-red/node\_modules/elasticsearch/src/lib/log.js:225:56) at checkRespForFailure (/home/workdb/.node-red/node\_modules/elasticsearch/src/lib/transport.js:258:18) at HttpConnector.

Hey Nicolas, Are you sure your Elasticsearch node is up and running? You can curl it? ---

Hey Thomas, thank you for the reply! I made some tests in the terminal using node.js as elasticsearch guide ([https://www.elastic.co/guide/en/elasticsearch/client/javascript-api/current/quick-start.html](https://www.elastic.co/guide/en/elasticsearch/client/javascript-api/current/quick-start.html)) tells, and everything goes well. Now I'm trying to connect Node-RED to Elasticsearch for send data from a function in Node-RED to Elasticsearch for use this data in Kibana. I am using some libraries from Node-RED to connect with ES, but I thing that I am missing something. Sometime after some changes, I received this error: "ReferenceError: documentType is not defined", and I been wondering, is it an error in Node-RED or ES? 😕 ![9ad96ab26258bbca4cadc40a1348be0f314c7af9_1_690x378](https://us1.discourse-cdn.com/elastic/original/3X/4/6/469d6b2bea64b911526962a26d43d25b407bf330.png) ![6379740a34145847b61f27d961bbd5b6cb555c61_1_690x378](https://us1.discourse-cdn.com/elastic/original/3X/2/b/2ba105819d88768f727ac1708fcc2588b7d40cb0.png) ![58c798147d43d9309ff7688f1cb4744710836667_1_690x378](https://us1.discourse-cdn.com/elastic/original/3X/e/0/e0b0e17592f324ced4435c80d7f9318644a3fb6a.png) ---

Nicolas, Node-RED is beyond my scope, so please bear with me as I attempt humble troubleshooting. FYI, the pictures are really hard to see unforunately. I'm glad to hear things are up and running now and you have connectivity! I've [found this flow](https://flows.nodered.org/node/node-red-contrib-elasticsearch-jd), which may be the very one you are using, if not it might be worth a quick look. Based on the error it sounds like you're not defining the document type. Referencing that link I provided, it looks like regardless of the usage, create/delete/search/etc..., `msg.documentType` should be set in an incoming message unless it was configured in the node. ---
