I am integrating Okta in my React application for SSO. I use the following method to create token using redirect:
https://github.com/okta/okta-auth-js#tokengetwithredirectoptions
I am using https://www.npmjs.com/package/@okta/okta-auth-js package.
Users are directed to the Identity Provider (idp) in order to authenticate and then redirected to Okta once verification is successful.
The SSO works fine but when I keep the React application idle for sometime, I am getting the following error:
OAuthError - Unable to process the username transform. A required property is missing. Missing field email.
It looks like you have configured email as the incoming claim from your IDP but Okta can't find it in the incoming assertion/token.
