Basic Authentication not working via python client

[tfinan (Tim Finan)]

I have been experimenting with some very simply python code to interact with Elasticsearch. Up
until a couple of days ago, everything was working great. I could add data to an index, read from
the index, search, etc....
However, suddenly today, I am getting this error:

AuthenticationException: AuthenticationException(401, 'security_exception', 'missing authentication credentials for REST request [/albums/_doc/6]')

from this code:

from datetime import datetime
from elasticsearch import Elasticsearch

es = Elasticsearch('http://localhost:9200', basic_auth=("elastic","Elastic"))
resp = es.get(index="albums", id=6)

Not only have I not made any authentication changes on the server, If I do the very same
REST queries via either the Elasticsearch Dev Tool Console, or via Postman, they work just
fine (with the exact same credentials).

I am just getting started using the python client code, so this is really making me pull my
hair out. Any help would be appreciated.

Hello! What is the major version of the libary you're using (elasticsearch.__version__)?

If it starts with 7... then you should use http_auth=("username", "password") instead of basic_auth=.... The basic_auth=... parameter was only added in v8.0.0.

Thanks, that definitely fixed it, but it is weird, because basic_auth was working fine just a couple of days ago. I did install Elasticsearch-dsl since then, so I am now wondering of I may have already had v8.0 installed, but Elasticsearch-dsl somehow downgraded me to v7?

Thanks for your help.
