Because of various disagreements between AWS and ElasticSearch, AWS released a fork called OpenSearch but and Elastic updated their clients to throw errors if you try to use them with this product.

This is obviously really annoying if you are using 3rd party software which uses the Elastic libraries, but trying to run them against AWS managed services. The following hack fixes this for Python elasticsearch v7.17 at least, by disabling the unnecessary version check:

# Hack elasticsearch to work with AWS
from elasticsearch import Transport
Transport._do_verify_elasticsearch = lambda self, headers, timeout: None
