Answer 1

You need to set ItemId, in example from form:
$builder
->add('name')
->add('startDate')
->add('itemId') //add this line
->add('endDate')
->add('description')
->add('preRequisites')
->add('picture','file')
->add('acquiredKnowledges')
->add('status')
->add('video', new VideoType())
;
or change nullable value to true
/**
* #var integer
*
* #ORM\Column(name="item_id", type="integer", nullable=true) //here nullable to true
*/
private $itemId;
