migration plugin works but fail to migrate in drupal database

Question

I try to migrate old blog article to a drupal website here is my migration class :

class Article extends SqlBase {

  /**
   *{@inheritDoc}
   */
  public function query() {
    $query = $this->select('news', 'n')
      ->fields('n', array(
        'id',
        'title',
        'content',
      ));
      return $query;
  }

  /**
   * {@inheritDoc}
   */
  public function fields(){
    $fields = array(
      'id' => $this->t('Autoincrement ID'),
      'title' => $this->t('Article name'),
      'content' => $this->t('HTML content'),
    );
    return $fields;
  }

  /**
   * {@inheritDoc}
   */
  public function getIds() {
    return [
      'id' => [
        'type' => 'integer',
        'alias' => 'n',
      ],
    ];
  }
}

my migrate_plus.migration.article.yml :

#Migration metadata
id: article
label: Migrate list of articles
migration_group: article_migration

#Source plugin, id defined in the @MigrateSource annotation
# in the src/Plugin/migrate/source/Article.php file.
source:
  plugin: article
  key: migrate

 # Process plugin
process:
  title: title
  body: content

# Destination plugin
destination:
  plugin: entity:node
  default_bundle: article



# Nothing needed here, it is a single table without any other relation.
migration_dependencies: {}

when i lunch drush ms i have this :

$ drush migrate-status
 --------------------------------------- ----------------------------------- -------- ------- ---------- ------------- ---------------
  Group                                   Migration ID                        Status   Total   Imported   Unprocessed   Last Imported
 --------------------------------------- ----------------------------------- -------- ------- ---------- ------------- ---------------
  article_migration (article_migration)   article                             Idle     290     0          290

  Default (default)                       block_content_type                  Idle     1       0          1

So the multiple database connection is working yet when i run $ drush migrate-import article

i have that error that i don't understant :

 [error]  Migration failed with source plugin exception: SQLSTATE[42000]: Syntax error or access violation: 1049 Unknown database 'jiyblog2&#039

article migration failed.
