Hi,

I'm using the kibana console to run queries. **Kibana and ES version 5.4**  
It worked fine, until I tried to enter some index templates.  
This is my query:

> POST \_template/my\_template  
> {  
> "template" : "_index_"  
> },  
> {  
> "mappings": {  
> "info": {  
> "properties":{  
> "Name": "text"}}}  
> }

The error I'm getting is this, in red:  
`#! Deprecation: Content type detection for rest requests is deprecated. Specify the content type using the [Content-Type] header.`

I haven't found much information on this error in google, does anyone know why it happens?

Thanks
