Hi Eric, It is not working fine as the length of the state can not be modified manually in IDCS.

Thank you for your information. Is there any feature I can check the error message? The login audit trail has no failure record. I posted the permission screenshot, I think there is no SAML related. I have tried to access it in two browsers - Chrome and Firefox. and cleared the browser cache. Still not working fine. Is it…

Thanks, Michelle. that is what I did. I got the answer, support center is not available as this env is for demo.

Let me try to clear my issue. Step 1: Open a browser type in https://<netsuite_id>.app.netsuite.com/app/login/secure/oidc.nl Step 2: It was redirected to the IDCS landing page; Step 3: After inputting the credential, it was redirected back to Netsuite and then running this error.

I can't find any information in the login audit trail, everything there is successful status, there is no other error information.

btw, I am facing is not “Netsuite as OIDC Provider”. that is IDCS as an identity provider. In Netsuite feature is called “OpenID Connect (OIDC) Single Sign-on”.

Thanks a lot. Emilia

Thanks, Mikko. I will try to do further investigation on the audit trail.
