Could not find external authentication provider registered

I’m trying to integrate Okta SSO with Umbraco CMS backend login.

The login bits works and it sends user out to Okta to key in the creds and then it calls back to our website. But upon calling back. I keep getting the below error message

“:“Could not find external authentication provider registered: {LoginProvider}”,”@l":“Warning”,“LoginProvider”:“https://xxxxxxxxx.okta.com”,

Anyone had any issues on the callback before similar to what’s happening?

Thanks
