i’m currently trying to deploy an API with its Opensearch “database” but i encounter problems :
My python API automatically crash when it tries to request Opensearch, here’s the log :

Modifying the Task execution role permissions doesn’t help. My API only tries to make _search queries. I’m using opensearch-py==2.6.0 to connect to my cluster :

hosts = [
    {'host': OPENSEARCH_HOST, 'port': OPENSEARCH_PORT}
]

proxies = {}
if OPENSEARCH_HTTPS_PROXY is not None:
    proxies['https'] = OPENSEARCH_HTTPS_PROXY
if OPENSEARCH_HTTP_PROXY is not None:
    proxies['http'] = OPENSEARCH_HTTP_PROXY

class MyConnection(RequestsHttpConnection):
    def __init__(self, *args, **kwargs):
        proxies = kwargs.pop('proxies', {})
        super(MyConnection, self).__init__(*args, **kwargs)
        self.session.proxies = proxies

es = OpenSearch(
    hosts,
    use_ssl=True,
    connection_class=MyConnection,
    http_auth=(OPENSEARCH_USERNAME, OPENSEARCH_PASSWORD),
    timeout=30,
    proxies = proxies
)
