The configuration was already broken and therefore you need to recreate the configuration

Solution:-
Remove the configuration from partner database eg if remove configuration is failing from primary try remove configuration from standby

DGMGRL> remove configuration
Removed configuration

If you try to create the configuration from standby you will encounter below error therefore please always create the configuration from current primary
