How to fix ElasticSearch 'Types cannot be provided in put mapping requests, unless the include_type_name parameter is set to true'

Problem:

You want to create a mapping in ElasticSearch but you see an error message like

elasticsearch.exceptions.RequestError: RequestError(400, 'illegal_argument_exception', 'Types cannot be provided in put mapping requests, unless the include_type_name parameter is set to true.')

Solution

As already suggested in the error message, set the include_type_name parameter to True.

With the Python API this is as simple as adding include_type_name=True to the put_mapping(...) call:

es.indices.put_mapping(index='my_index', body=my_mapping, doc_type='_doc', include_type_name=True)

In case you now see an error like

TypeError: put_mapping() got an unexpected keyword argument 'include_type_name'

you need to upgrade your elasticsearch python library, e.g. using

sudo pip3 install --upgrade elasticsearch
