Migrating CSV file with drush.

Hi!
I just triyinf to import a CSV file to create a taxonomy data on my Drupal 8.2.5.

That is the CSV file content:

Name,Description
"Name1","Title1"
"Name2","Title2"
"Name3","Title3"

This is my taxonomy categories
field_description
field_category_name

And my .yaml file has:

id: import_category
migration_tags: category_news
migration_group: categoryIMPORT
label: 'Category news migration'
source:
  plugin: csv
  path: /var/www/html/themes/wilmap/csv/categorynews.csv
  header_row_count: 1
  keys:
    - Name
process:
  field_description: Description
  field_category_name: Name
  type:
    plugin: default_value
    default_value: category_news
destination:
  plugin: entity:taxonomy_vocabulary
migration_dependencies:
  required: {  }
  optional: {  }

The issue I have is the nex one:
The entity does not have an ID. (/var/www/html/core/lib/Drupal/Core/Config/Entity/ConfigEntityStorage.php:248)

I need some help with that problem...

Thanks!
