3099382 - Blue screen appearing for dynamically created users

Dynamically created users are seeing blue screen after logging into SAC.

• SAP Analytics Cloud
• Custom Identity Provider 

1. Configure the SSO SAML and enable the dynamic user creation option  in SAC.
2. Logon to SAC tenant with the backend user.
3. A blue screen is appearing (No menu, no buttons are available).

• The 'preferredLanguage' attribute set in the custom Identity Provider has an invalid format which SAC does not understand.
• For instance, the IdP passes 'preferredLanguage' attribute as 'en-US', however the correct attribute for SAC would be 'en'. 

Change the 'preferredLanguage' attribute on the custom IdP side to 'en', so the correct value will be passed to SAC.
