The drush command drush smart_date:migrate workshop field_when field_core_daterange without the parameter --clear does not skip entities with default values, it throws an exception on the console and aborts:
SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '1-0-0-de' for key 'PRIMARY'
The documentation for the option --clear → says:
This happens when i configure a default value of default_date_type: now for the field but disable the field in form_display of my node. But i dont think it has anything to do with the field being disabled.

Thank you for your help. I tested the merge-request and the changes to the migrate-command work like expected now.
