I am trying to connect to Elasticsearch using the elasticsearch-dbapi library. I want to be able to execute SQL queries on my Elasticsearch cluster.
However, I keep getting this error when I attempt to run a query,

This is what my code looks like,
from es.elastic.api import connect
conn = connect(
host='https://<endpoint-alias>.es.eastus2.azure.elastic-cloud.com',
port=9200,
scheme="https",
user='elastic',

)
curs = conn.cursor()
curs.execute(

)
What exactly is the problem here?
Note: I am using the elasticsearch-dbapi package because although it is possible to execute SQL queries using elasticsearch, there does not seem to be an option to scan through all of the results. I want to access all the hits that are returned by a query.
However, when I tried connecting using elasticsearch, it worked without any problem. But, I used the Cloud ID to establish the connection. Is there some issue with the host that I have used?
I have a dataset with name "haberman.csv" in my current directory and upon trying to load the dataset with below load_dataset function then it throws an error saying HTTPError: HTTP Error 404: Not Found.
But when loaded a different dataset with name "tips.csv" in the same directory it works well.
What is the reason behind this error that one dataset when loaded works and another doesn't.

* The store could not be migrated to the current model version.
