Answer 1

Your indexes are still waiting for replica, which generally we avoid when working on a single node.

Run this command on your local host :

curl -XPUT 'localhost:9200/_settings' -d '{ "index" : { "number_of_replicas" : 0 } }'

This should change the index status to green and your program should be good to go.
