I try to import CSV files into a Drupal 8 installation but I can't manage to make the relationship to paragraphs appear. I followed the steps of this tutorial but can't figure out how to make it work. I created a simple test case to find the error:
I extended the regular article content type with a paragraphs field called field_persons for linking each article to a list of persons with roles. This paragraphs entity has to fields called field_name (for now only text) and field_role (taxonomy_term).
The yaml file for paragraphs migration looks like that and import processes without error:
id: article_persons label: Import persons for articles source: plugin: csv delimiter: '|' enclosure: '"' path: article_persons.csv header_row_count: 1 keys: - id column_names: 0: id: 'ID' 1: name: 'Name' 2: rol: 'Role' process: field_nombre: name field_para_rol: plugin: entity_generate source: role value_key: name bundle_key: vid bundle: rol entity_type: taxonomy_term ignore_case: true destination: plugin: 'entity_reference_revisions:paragraph' default_bundle: article_persons The yaml file for article migration looks like that and import processes without error:
id: article label: Import articles source: plugin: csv delimiter: '|' enclosure: '"' path: articles.csv header_row_count: 1 keys: - id column_names: 0: id: 'ID' 1: title: 'Title' 2: person: 'Persons' process: title: title type: plugin: default_value default_value: article field_person/target_id: - plugin: migration_lookup migration: article_persons no_stub: true source: id - plugin: extract index: - '0' field_person/target_revision_id: - plugin: migration_lookup migration: article_persons no_stub: true source: id - plugin: extract index: - 1 destination: plugin: 'entity:node' migration_dependencies: required: - article_persons optional: { } But when I try to access the node I get an "unexpected error" with a huge log message:

This bug report seems to indicate that the paragraphs which is referenced doesn't exist. So it seems to have to do something with the ids, but I can't figure out what.
