Content-Type header [application/x-www-form-urlencoded] is not supported on Elasticsearch

Question

I used to have ElasticSearch 5.2, and just upgraded to 6.0.

I am trying to create an index template following guide here, but got error

Content-Type         


        

Answer 1

The solution is to add Content-Type: application/json header

curl -XPUT 'localhost:9200/_template/template_1' \
  -H 'Content-Type: application/json' \
  -d '**your query**'
