title: Symfony 5.4 - Multiple upload image file with VichUploaderBundle - Column 'zdjecie' cannot be null
body: <p>I am using EasyAdmin 4.0 and Symfony 5.4.
  My goal was to upload photos and assign them to Entity Game - as a photo gallery.
  We have Entity Game and Entity Zdjecie.
  OneToMany Report - One Game can have many photos.
  I used the tutorial from YT: <a href="https://www.youtube.com/watch?v=dKX_yREDOmQ" rel="nofollow noreferrer">https://www.youtube.com/watch?v=dKX_yREDOmQ</a></p>
  <p>I'm already using the Vich Uploader library - Entity The game has a 'thumbnail' (in polish 'miniaturka' field that stores the name of the photo displayed as a thumbnail and that works fine.
  When adding a new Game object, the following message appears:
  An exception occurred while executing a query: SQLSTATE [23000]: Integrity constraint violation: 1048 Column 'zdjecie' cannot be null
  'INSERT INTO photo (photo, update_date, id_gra_id) VALUES (?,?,?)', Array (null, object (DateTimeImmutable), 44), array ('string', 'datetime', 'integer'))
  In fact, when I did dd (...) on the object, the value &quot;photo&quot; is null.
  In my code - 'zdjecie', 'zdjeciePlik' corresponds to the names from the tutorial 'image', 'imageFile'.</p>
  <p>Has anyone encountered such a situation? I saw a many post for VichUploader but not work ;/</p>
  <p>Possibly recommends a different method of multiple uploads of photos for one Entity?
