Hi Friends,  
I am new to elastic search and looking for lep!  
I am trying to create mapping , buy using the same JSON at URL [https://www.elastic.co/blog/analyzing-network-packets-with-wireshark-elasticsearch-and-kibana](https://www.elastic.co/blog/analyzing-network-packets-with-wireshark-elasticsearch-and-kibana)  
using curl command

curl -XPUT [https://xxx.us-east-1.es.amazonaws.com/ciscofeed/packets/\_mapping](https://xxx.us-east-1.es.amazonaws.com/ciscofeed/packets/_mapping) -d @mapping.json

but it is throwing below exception

{"error":"Content-Type header [application/x-www-form-urlencoded] is not supported","status":406}

My Index url [https://xxxxxx.us-east-1.es.amazonaws.com/ciscofeed?pretty](https://xxxxxx.us-east-1.es.amazonaws.com/ciscofeed?pretty)

Out of above curl command  
{  
"ciscofeed" : {  
"aliases" : { },  
"mappings" : { },  
"settings" : {  
"index" : {  
"creation\_date" : "1547416048805",  
"number\_of\_shards" : "5",  
"number\_of\_replicas" : "1",  
"uuid" : "7nrSmfnqR\_mKhdfUxUYZ4g",  
"version" : {  
"created" : "6030199"  
},  
"provided\_name" : "ciscofeed"  
}  
}  
}  
}

Thanks

Try adding `-H'Content-Type: application/json'`.
