Briefly, this error occurs when the Elasticsearch node name is automatically derived from the node ID and is set to override any existing node name. This could be due to a configuration issue or a node ID conflict. To resolve this, you can manually set a unique node name in the Elasticsearch configuration file (elasticsearch.yml) using the ‘’ parameter.
