Unable to get SAML to work after upgrade

Hello, I’m having issues configuring SAML with Azure IDP. It was working before, but it broke after upgrading my stack from 7.6.1 to 7.10.2. Now I can’t get it to work. Here is my saml config:

  saml_auth_domain:
	http_enabled: true
	order: 1
	http_authenticator:
	  type: saml
	  challenge: true
	  config:
		idp:
		  metadata_url: https://login.microsoftonline.com/026419...9bd3-5ae9a9aa02fa/federationmetadata/2007-06/federationmetadata.xml?appid=2531...b141
		  entity_id: https://sts.windows.net/0264190...aa02fa/
		sp:
		  entity_id: kib-saml
		kibana_url: https://C04-KIB801-01:5601/
		roles_key: "Role"
		exchange_key: bdaaa...165754
	authentication_backend:
	  type: noop

Applying the config is successful, but I get the following error in the logs:

What I find odd is /etc/elasticsearch/https:/login.microsoftonline.com Anyone has any idea?

Thank you,
