AWS Opensearch and NEST


I am trying to connect to Opensearch Version 1.3 using the .net NEST library 7.17 from a .net Core app and I get the error:

Elasticsearch.Net.UnsupportedProductException: 'The client noticed that the server is not Elasticsearch and we do not support this unknown product.'

I tried downgrading to NEST 7.14.1 same issue! Any help would be much appreciated!

Hi, it seems like the dot net client library(NEST) is not updated with OpenSearvch V1.3

The OpenSearch project was first announced in January 2021 as an open-source fork of Elasticsearch 7.10.2.

Please enable the compatibility mode in the OpenSearch domain and try again with NEST.

Following command will enable compatibility mode in existing OpenSearch domain:

PUT /_cluster/settings
  "persistent" : {
    "compatibility.override_main_response_version" : true

Compatibility Mode
