Can't specify parent if no parent field has been configured

Elastic Stack Elasticsearch

Hi to all

I have the following problem with this example suggested by the book "ElastiSearch Cookbook" in my ElasitcSearch 2.1

The error is: Can't specify parent if no parent field has been configured what's wrong?

This is the list of commands to execute:
