I am trying to use SSO with an OpenID appliciation I have created in Okta but I am getting this error -
Not sure if anyone has seen this or has any clue as to what may be happening. I followed the Okta Python Flask app creation guide and everything else seems to be functioning normally.

Hello @User16455543062308508348 (Customer)
Thanks for posting.
Using the URL of the form https://org.okta.com/oauth2/default/v1/authorize requires an additional paid feature of API Access Management which is used for custom authorization servers.
Instead use the URL https://org.okta.com/oauth2/v1/authorize to access the default authorization server for Okta without API Access Management.
