elasticsearch 6.0.0 is [EOL](https://www.elastic.co/support/eol) and no longer supported. Please upgrade ASAP. (This is an automated response from your friendly Elastic bot. Please report this post if you have any suggestions or concerns :elasticheart: ) ---

Hi @Alex_Salgado-Elastic Elasticsearch Version -- 7.2.0 Elasticsearch library version is -- 7.0.0 Python Version 3.10.9 When I Perform any query individually It works well. But, When I Working on Flask API at the line of query It generates the error like that hits = esconnection.search(index=index\_name, \_source=projection, body={"size": size, "from": skip, "track\_total\_hits": True, "query": search\_query, "aggs": aggregation}) Connection -- esconnection = Elasticsearch(hosts="localhost", port=9200, http\_auth=("username", "password"), timeout=60) Thank you. ---

Hi @Anand_Konagala I would recommend that you update your client versions: pip install elasticsearch Create this small program to test (elastic-test.py) ```auto from elasticsearch import Elasticsearch # Create the client instance client = Elasticsearch( [{"host":"localhost", "port":9200}] ) # Successful response! print(client.info()) ``` And see if it is returning the correct result If so, test the same code within Flask and compare the environments. ---
