I have a freshly composer installed Drupal 8.6.13. I tried to migrate csv sources and allways got the error message
[error] Migration failed with source plugin exception: id is defined as a source ID but has no value.
I switched to an example that is running in another installation https://www.drupal.org/docs/8/api/migrate-api/migrate-source-plugins/migrating-data-from-a-csv-source, but still get this error.
My versions: migrate 8.6.13, migrate_plus 8.x-4.1, migrate_source_csv 8.x-2.2, migrate_tools 8.x-4.1
Does anyone have an idea what causes the error?
This are the files:
