We are using the latest SAML20 module in our app (in studio pro 8.8.1) for SSO via Okta. The "IdP Initiated Authentication" option is enabled in SSO configuration. When SSO is initiated from the application by going to https://hostname:port/SSO/, it works fine, where the SAML response contains the InResponseTo element. When Okta (IdP) initiates the request, where the SAML response doesn’t contain the InResponseTo element, it fails with on-screen message "Unable to validate the SAML message", and the application log shows errors: "ERROR - SAML_SSO: java.lang.NullPointerException: null" and "ERROR - SAML_SSO: Unable to validate Response, see SAMLRequest overview for detailed response. Error: null". We wonder if we missed any configuration that would make Idp Initiated Authentication work. Thanks!
