Email notifications are typically based on Email Templates. You can access these templates via the UI configuration gear icon -> Email Templates. Each of these templates utilize an internal parameter "$ENTITY_URI". This article refers to the value used by the $ENTITY_URI being used/interpreted by CDD when notifications are being sent.
This parameter is based on settings in the CDD_HOME/conf/settings.properties file. Specifically, it is controlled by the following lines in that file:
Release : 7.1
Component : CONTINUOUS DELIVERY DIRECTOR
Change the appropriate lines in the $CDD_HOME/conf/settings.properties file to utilize the appropriate values for you and your organization.
