How to connect Django Backend and Elastic Search under ver 8.8.1?

[CodingKirby8620]

Issue

I'm using Django 4.2 and Elastic Search 8.8.1, I don't know how to make ES 8.8.1 available in my django project.
It seems that strict security system is implied in ES 8.8.1, sad for beginner :(

This screenshot above is the issue I met... at least for now


above is settings.py


pip3 list

I'm using the following settings in my production:

ELASTIC_USERNAME = os.getenv('ELASTIC_USERNAME')
ELASTIC_PASSWORD = os.getenv('ELASTIC_PASSWORD')
ELASTICSEARCH_DSL = {
    'default': {
        'hosts': 'https://elasticsearch:9200',
        'http_auth': (ELASTIC_USERNAME, ELASTIC_PASSWORD),
        'verify_certs': True,
        'ca_certs': '/app/certs/ca/ca.crt',
    },
}

use_ssl - is not valid parameter. Here you can find all parameters it accepts: https://github.com/elastic/elasticsearch-py/blob/main/elasticsearch/_sync/client/__init__.py#L131

note the hostname elasticsearch in my 'hosts': 'https://elasticsearch:9200', comes from my docker-compose file:
