问题
I am trying to run the below code in Python using Elasticsearch Ver 7.1, however the following errors come up:
ElasticsearchDeprecationWarning: [types removal] Using include_type_name in put mapping requests is deprecated. The parameter will be removed in the next major version.
client.indices.put_mapping(index=indexName,doc_type='diseases', body=diseaseMapping, include_type_name=True)
followed by:
ElasticsearchDeprecationWarning: [types removal] Specifying types in document index requests is deprecated, use the typeless endpoints instead (/{index}/_doc/{id}, /{index}/_doc, or /{index}/_create/{id}).
client.index(index=indexName,doc_type=docType, body={"name": disease,"title":currentPage.title,"fulltext":currentPage.content})
How I am supposed to amend my code to make it (see here) work in line with Elasticsearch 7X version? Any kind of help would be much appreciated.

This is just a warning right now, but it will become an error in Elasticsearch 8.
From last few version, Elasticsearch has been planning the removal of index types inside an index
- ES5 - Setting index.mapping.single_type: true on an index will enable the single-type-per-index behavior which will be enforced in 6.0.
- In ES6 - you can't have more than 1 index type inside 1 index
- In ES7 - the concept of types inside an index has been deprecated
- In ES8 - it will be removed, and you can't use types for query or while inserting documents
My suggestion would be to design an application and mapping in such a way that it doesn't include type parameter in index
To know the reason why elastic search has done this here is a link: https://www.elastic.co/guide/en/elasticsearch/reference/current/removal-of-types.html#_why_are_mapping_types_being_removed

A common issue (and difficult to spot) for this error message could be misspelling the endpoint, e.g.:
Misspelled:
/search
Correct:
/_search
Double check if your endpoint is correct as ElasticSearch may think you are trying to manipulate (add, update, remove) a document and you are giving a type, which is not the case (you are trying to call an endpoint).
