SSL error while doing a request for Microsoft graph api

I trying to get integrate Microsoft Graph API into the airflow application docker-compose. And I have a self-signed SSL certificate for my domain.

following is the sample of DAG (pythonOperator): [I'm using the msal pypi package]

app_meta = MicrosoftGraphAPI.get()
app = msal.ConfidentialClientApplication(
   app_meta['client_id'],
   authority=app_meta['authority'],
   client_credential=app_meta['client_credential'],
   token_cache=None,
)

Error:

    WARNING - Retrying (Retry(total=0, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError(SSLError("bad handshake: Error([('SSL routines', 'tls_process_server_certificate', 'certificate verify failed')])"))': /d8c857c0-b2da-48fd-9b28-db5792c0d481/v2.0/.well-known/openid-configuration

UPDATE: I don't want to ignore certificate validation. How to fix it

Earlier intermediate CA certificates were optional, but now it is mandatory that you must have all the root and intermediate certificates available in certificate chain. I also faced this issue while connecting to nuget site for downloading packages, so i installed "BaltimoreCyberTrustRoot" , "Microsoft Azure TLS Issuing CA 01" and "DigiCertGlobalRootG2". It worked for me.
