Error: The value "" is not an item.

I'm having trouble trying to import medias with "CSV - Medias". My csv is like this.

dummy,item,url
,id-003,https://example.com/id-003-image.jpg
,id-004,https://example.com/id-004-image.jpg

The error message is 'The value "" is not an item.'.

src/Processor/ResourceProcessor.php:350

            case 'o:item':
                $identifier = array_pop($values);
                $identifierName = $target['target_data'] ?? $this->bulk->getIdentifierNames();
                $itemIds = $this->bulk->findResourcesFromIdentifiers($values, $identifierName, 'items', $resource['messageStore']);

When a single item identifier is in $value array, $value will be [] after array_pop() and [] will be passed as the first argument to findResourcesFromIdentifiers(). As a result, no item will be found.

I don't know this is intended behavior or not, but when I use end() instead of array_pop() or pass [$identifier] instead of $values, the import is successful.

Could you please check this?

Thank you for your great work.
