WARN Content type detection for rest requests is deprecated

Elastic Stack Elasticsearch

I'm seeing a lot of these warnings in our logs, can anyone tell me what they are, and where they are coming from?

[2017-06-21T09:36:18,650][WARN ][org.elasticsearch.deprecation.rest.RestController] Content type detection for rest requests is deprecated. Specify the content type using the [Content-Type] header.

You need to specify the content type.

How are you inserting documents in elasticsearch?

We're using the PHP vendor v5.2.0

4

Upgrade. It might be fixed now.

5

v5.2.0 is the latest release of the vendor..., or do you mean upgrade the cluster?

6

No I meant update the client.

7

Why do you mean by PHP Vendor BTW?

I think @polyfractal can help here.
I don't see an issue in the repo related to this.

Hm, the client should be setting the content-type correctly, see here: https://github.com/elastic/elasticsearch-php/blob/master/src/Elasticsearch/ClientBuilder.php#L480

@barry1 can you open an issue at the Elasticsearch-PHP github repo with your details? We can work through your problem there
