if I use this code
$sampleContent = $objectManager->create(\Magento\Downloadable\Api\Data\File\ContentInterfaceFactory::class)->create();
$sampleContent->setFileData(
@codingStandardsIgnoreLine
base64_encode(file_get_contents( '/var/www/html/jellyfish_1_3.pdf'))
);
$sampleContent->setName('jellyfish_1_3.pdf');
$sampleContent->setType('application/octet-stream');

$upload =$objectManager->create(LizardMedia\ProductAttachment\Api\Data\File\ContentUploaderInterface::class);
$upload->upload($sampleContent,"file");

I get the following error:
PHP Fatal error: Uncaught Magento\Framework\Exception\RuntimeException: Type Error occurred when creating object: Magento\MediaGalleryIntegration\Plugin\SaveImageInformation, Argument 6 passed to Magento\MediaGalleryIntegration\Plugin\SaveImageInformation::__construct() must be of the type array, null given, called in /vendor/magento/framework/ObjectManager/Factory/AbstractFactory.php on line 121 in /vendor/magento/framework/ObjectManager/Factory/AbstractFactory.php:131

What can I do?
