Update your Tools support Elasticsearch version 7 APIs
Deprecated index document types
The ability to specify a custom document type has been deprecated in Elasticsearch version 7. A full list of mapping changes can be found at
Deprecated version 5 example with a custom document type:
curl -X PUT 'http://<elasticsearch>/index_name' -d '{ "mappings": { "custom_type": { "properties": { "foo": { "type": "keyword" } }, } } }'
Supported version 7 example:
curl -X PUT 'http://<elasticsearch>/index_name' -d '{ "mappings": { "doc": { "properties": { "foo": { "type": "keyword" }, }, } } }'
This mapping change also effects the path to your index documents.
Example index document paths
Deprecated version 5
PUT <index>/<custom type>/<id>
version 7
PUT <index>/_doc/<id>
