Hello Ramakrishna,
Thanks for submitting your question to the Help Center. Okta Support would benefit from looking at your direct configuration in both Okta and AWS, so we would recommend opening up a case so we can connect directly with you. Please use the Open a Case button on the Help Center, or reach out to the support team by phone.
Thanks!
