SAML2: error performing test conneciton java.lang.ClassCastException: org.mozilla.javascript.ConsString cannot be cast to java.lang.String: no thrown error

Cause Check if System property "glide.authenticate.multissov2_feature.enabled" is set to true.

Then check 'Single Sign-On Script' field in IDP configuration is set as 'MultiSSO_SAML2_Update1' instead of 'MultiSSOv2_SAML2_custom'

Resolution Change the 'Single Sign-On Script' field to use 'MultiSSOv2_SAML2_custom' (instead of 'MultiSSO_SAML2_Update1') due to 'glide.authenticate.multissov2_feature.enabled' being enabled. After this change, test connection should work fine.
