+   If you encounter dependency conflicts while installing Elasticsearch 8, particularly with `psr/http-message`, you can resolve this by following these steps:
+
+   1. First, require the Elasticsearch 8 module without updating other dependencies:
+
+      ```bash

+
+      ```bash
+      composer update magento/module-elasticsearch-8 aws/aws-sdk-php -W
+      ```
