i need to make an import from one mysql table in my base.

I create node with :

$value= array(                 'type' => strtolower($typeProduit),                 'field_1'=>"test",                 'title'=>"test",                 'body' => array(                     'value' => "test",                     'format' => 'full_html',                 ),                 'field_2'=>"",                 'field_3'=>"",                 'field_4'=>"",                             );   $nodeEntity=Drupal::entityTypeManager()         ->getStorage('node')         ->create($value);      $nodeEntity->save(); 

All node are create and if i have an image, i add it to my $value before save() :

$value['field_image_video']=array(                     'target_id' => $fileImageVideo->id(),                     'alt' => $catalogue->titreVideo,                     'title' => $catalogue->titreVideo,                 ); 

if i have no image, i do nothing for this field.

I need to update some node programmatically after this first step.

And when i just try to change the title like this :

     $nodeEntityUpdate = Drupal::entityTypeManager()                     ->getStorage('node')                                     ->load(273);       $nodeEntityUpdate->title="blabla";      $nodeEntityUpdate->save(); 

if node don”t have image field set, i got this error :

PHP Fatal error: Call to a member function getFileUri()

If node has image, update work.

How can i set my image_field to null ?

i try to set my image field like that on creation :

$value['field_image_video']=array(); 

But that didn’t work.

this image field is set to unlimited values
