Hi there,
Thank you for reaching out to us!
We are trying to reply to older posts, in case other encounter the same issue and we can provide some more information. Allow me to provide some additional documentations that cover the setup of Okta as an IdP with Auth0, that are more updated and could be more useful in this case :
- https://auth0.com/docs/authenticate/protocols/saml/saml-sso-integrations/configure-auth0-saml-service-provider/configure-okta-as-saml-identity-provider
- Setup SSO for Auth0 Sample App With Okta As IdP

Hope this helped!
