I’ve been facing a problem while integrating OIDC. After okta login is completed, redirection to my callback url (response_type is form_post) results in a 403 error due to null origin in the request (only whitelisted origins are allowed from my gateway). On further digging I found referrer-policy: no-referrer from /authorize endpoint. I have added my website’s hostname to trusted origins in okta dashboard, still the problem persists.
Referer-Policy = ‘no referrer’ shouldn’t cause any issues.
Could you please check if you can see the ‘Referer’ in the request header for the /authorize endpoint? Also, make sure that your website’s domain or host name (the URL you whitelisted in the Okta admin console) is set to ‘Referer’.
