Authentication error in the Decision Data Store landing page

Suggest edit Updated on March 11, 2021

If you do not specify user credentials for connecting to an external Cassandra database or if the credentials are incorrect, the Decision Data Store (DDS) landing page displays an authentication error.


The DDS landing page displays the following error:
