Questions OAuth/OIDC

Hi,
i am trying to do poc with okta. i have saml -application in okta which could fetch custom profile from
the okta profile and return.

I planned to consume this app saml response . at present it prompt okta user/password and redirected to my local app and show profile and working fine. i plan to fetch results by OAUTH2 login. i am able to generate authcode from the
Identity provider. my requirement instead okta asking for user/password i plan to use OAUTH2 to authorize and
allow to show custom profile in my end app with out prompting user/password.

below is my details.

0oaalvrh7iLJX0FUQ0h7 - my OAUTH2 identity provider

client id of OPENID - 3pgiRciiwvdG6bHru52e

i could see below error always “The authorization server encountered an unexpected condition that prevented it from fulfilling the request”
i showing login page initially and then my call got interrupted by above error and then it prompt login again.

I’m having a hard time following what you are attempting to do, what does SAML have to do with the flow you are attempting?

Try the following (I’m doing generic troubleshooting here, I still am unsure of what you are doing):

  • Remove the idp parameter (does it work without it?) if it does work are you using SAML? Social?
  • Try URL encoding the query parameters, this could cause an unexcepted error
