Migrate images from non Drupal source to node destination

I want to migrate external database table (not of a drupal website) to node destination having the content type : 'company_profile'
the migration is done except the image field witch has the machine name 'field_company_image'.

this is the class :

class SwMigrateCompanyProfileMigration extends BaseMigration {
  public function __construct($arguments) {
    parent::__construct($arguments);
    $this->description = t('Company Profiles (tx_exinitjobexchange_profiles).');
    
    // Add remote database connection
    Database::addConnectionInfo('sw_typo3', 'default', array(
        'driver' => 'mysql',
        'database' => TYPO3_DATABASE_NAME,
        'username' => TYPO3_DATABASE_USERNAME,
        'password' => TYPO3_DATABASE_PASS,
        'host' => TYPO3_DATABASE_HOST,
        'port' => '3306',
        'prefix' => '',
    ));
    
    // Active connection to the database 
    db_set_active('sw_typo3');
    
    $this->map = new MigrateSQLMap($this->machineName,
        array('uid' => array(
                'type' => 'int',
                'not null' => TRUE,
                'description' => 'tx_exinitjobexchange_profiles ID.'
                )
            ),
        MigrateDestinationNode::getKeySchema(),
        'sw_typo3'
    );
    
    
    // Connect to the remote $databases
    $query = Database::getConnection('default', 'sw_typo3')
        ->select(TYPO3_DATABASE_NAME.'.tx_exinitjobexchange_profiles', 'cp')
        ->fields('cp', $this->queryParams['company_profile']['fields'])
        ->orderBy($this->queryParams['company_profile']['order_field'], $this->queryParams['company_profile']['order_field_operator']);
    $query->condition('cp.fe_user', 0, '<>');

    // Define source and destination for migration
    $this->source = new MigrateSourceSQL($query);
    $this->destination = new MigrateDestinationNode('company_profile');
    
    /*** Make the mappings ***/
    $this->addFieldMapping('title', 'company');
    $this->addFieldMapping('is_new')->defaultValue(TRUE);
    
    // uid field
    $this->addFieldMapping('uid', 'fe_user')->sourceMigration('SwMigrateFeUser');
    
    // field_company_image
    $this->addFieldMapping('field_company_image', 'logo')
        ->sourceMigration('SwMigrateCompanyProfileLogo');
    $this->addFieldMapping('field_company_image:file_class')
        ->defaultValue('MigrateFileFid');
    $this->addFieldMapping('field_company_image:language')
     ->defaultValue('de');
    
    $this->addFieldMapping('created', 'crdate');
    $this->addFieldMapping('changed', 'crdate');
    $this->addFieldMapping('status')->defaultValue(1);
    $this->addFieldMapping('promote')->defaultValue(0);
    $this->addFieldMapping('sticky')->defaultValue(0);
    $this->addFieldMapping('language')->defaultValue('de');
 
    $this->addFieldMapping('path')->issueGroup(t('DNM'));
    $this->addFieldMapping('comment')->issueGroup(t('DNM'));

    
    // Back to local database again!
    db_set_active('default');
  }

}

The class that import images (logo) is called "SwMigrateCompanyProfileLogoMigration" that's why I added the source migration when mapping the image field :
$this->addFieldMapping('field_company_image', 'logo')->sourceMigration('SwMigrateCompanyProfileLogo');
And the migration of the image files are done succefully (I can see them inside default/files directory, also inside "file_managed" database table are succesfully inserted!)

But, when I edit the nodes I don't find the image field filled up (the table "field_data_field_company_image" is empty !)

How can I improve this class or what im missing to make this relationship working ?
Thanks in advance.
