Authentication Ticket value null in Authorization Code Received Event

Questions

Hi team,

I am integrating OKTA PKCE authentication in Sitecore web application. I am able to authenticate the user however in the ProcessAuthorizationCodeReceived event
notification.AuthenticationTicket is coming null. Due to this I am not able to proceed with next steps in the Sitecore pipeline. I am able to generate the Token,UserInfo and Notification using below code.

var args = new OktaPostAuthorizationArgs()
{
Token = tokenResponse,
UserInfo = userInfoResponse,
Notification = notification,
};

please let me know why AuthenticationTicket value is coming null from OKTA.

Thanks,
Alok…

Hi Alok, did a quick search about your error message and some results indicate that it might be an issue with how your response_type is configure. Can you taking a look at the article from and see if changing the response_type helps? https://stackoverflow.com/questions/40830687/accesstoken-is-null-for-identity-server-client

If we are using Response type as ‘Code’ which needs to be only the expected value if grant type as declared ‘authorization code’ in Okta. we do not get value of authentication ticket if we follow the above process?
