If you are using Python elasticsearch client, you need to downgrade or install version before 7.14.0.

pip install 'elasticsearch<7.14.0'

It worked fine after degrading to elastic search < 7.14. So basically added a gem to restrict the version upgrade

gem elasticsearch, "< 7.14" 

Elasticsearch::UnsupportedProductError is raised when your Elasticsearch server version don't match with Ruby's Elasticsearch client (gem elasticsearch). In order to fix this properly you need a server that is up to date with latest Elasticsearch (ES) releases

that means if you are on ES provider like where you work with latest versions of cluster it's easy peasy => server gets upgraded => this is not an issue

if you however work with provider that is slow to catch up with latest ES releases (like AWS Elasticsearch / AWS Opensearch where last version is 7.10 and will not get upgraded anytime soon) your only option is to use gem elasticsearch, "< 7.14" (Siddhant's answer in this discussion ...and yes this means no potential security updates

other solution may be to silence the verification by overriding method verify_with_version_or_header as proposed in

but reality is both of this solutions are just "not recommended" workarounds. The real fix is a server upgrade
