Magento is running on an AWS EC2 instance. AWS Elasticsearch version is 6.0, and Magento is 2.3.4.

Connectivity is successful when I check the connectivity to AWS Elasticsearch via Stores > Settings > Configuration > Catalog > Catalog > Catalog. I am using

When I do bin/magento indexer:reindex catalogsearch_fulltext I get following error

Catalog Search indexer process unknown error: {"error":{"root_cause":[{"type":"illegal_argument_exception","reason":"request [/magento2_product_1_v2/_mapping/document] contains unrecognized parameter: [include_type_name]"}],"type":"illegal_argument_exception","reason":"request [/magento2_product_1_v2/_mapping/document] contains unrecognized parameter: [include_type_name]"},"status":400}

Any help please?

I also encountered this problem because the version of elasticSearch is too low, and it can be solved by upgrading to version 6.8 or higher.

  • I got this error while re-indexing on bitnami server with magento version 2.4. I checked and found ES version 6.5.3.
  • I got to magento->admin->stores->configuration->catalog->catalog
    search->Search Engine->... and selected "Elasticsearch 6.x (Deprecated)".
  • Flushed the cache and re-index again and successful.


  • strange one, it worked for me as well even though I am running 7.10.2 of elastic search
