The PutElasticsearch processor uses the Transport API for Elasticsearch, not the HTTP API. This means your port should be 9300 not 9200.

The "Identifier Attribute" property is the name of a flow file attribute that contains a unique identifer for the document. If you don't have an identifier you want to use, you can put "uuid", this will use the flow file's UUID as the identifier for the Elasticsearch document. If you do have an identifier for the document, put its value (using UpdateAttribute, EvaluateJsonPath, etc.) into a flow file attribute, and put that attribute's name in the "Identifier Attribute" property. Note you don't use Expression language here, so if your attribute's name is "doc_id", you put "doc_id" in the Identifier Attribute property, not "${doc_id}"
