I am trying to use the deriver key in a migration yml to have dynamically build migrations for each bundle of an Entity Type (Drupal 9).
I read this and I am trying to use the deriver key to point to a Deriver class in my migration. However it seems that the deriver key is just ignored.
Is there something else that I need to do beside using the deriver key and create a deriver class that inherits from DrupalComponentPluginDerivativeDeriverBase?
This is the migration yml:
id: person_roles label: Import deriver: Drupalmy_modulePersonRoleImportDeriver migration_group: my_group source: plugin: url data_fetcher_plugin: http data_parser_plugin: xml urls: public://this.xml fields: - name: position_name label: person role name selector: funktion ids: position_name: type: string destination: plugin: 'entity:my_entity' process: name: - plugin: skip_on_empty method: row source: position_name message: 'Empty source person role' - plugin: make_unique_entity_field entity_type: my_entity migrated: true field: name
