I have created a yml configuration for migration from CSV source into drupal using composer. After running the "drush migrate:import mbe_book_paragharphs", I am getting the error as You must declare "ids" as a unique array of fields in your source settings.
I am using migrate_source_csv 8.x-3.1
id: mbe_book_paragharphs migration_group: mbe_migrations label: 'Import book paragraph' source: plugin: csv path: '/var/www/html/drupal/author.csv' header_row_count: 1 ids: [id] process: field_mbe_title: Title field_mbe_author: Author destination: plugin: 'entity_reference_revisions:paragraph' default_bundle: mbe_book migration_dependencies: null
I need help on how to resolve this issue
In the YML configuration file, instead of "ids", i was using "keys" before but was getting the same error
