[Bug] When setting 'System Key' with empty value, import just dies

[fashxp]

Expected behavior

get a error message into application logger, and not just having importer stuck

Actual behavior

13:23:37 WARNING   [messenger] Error thrown while handling message Pimcore\Bundle\DataImporterBundle\Messenger\DataImporterMessage. Sending for retry #3 using 4000 ms delay. Error: "Handling "Pimcore\Bundle\DataImporterBundle\Messenger\DataImporterMessage" failed: Pimcore\Model\DataObject\AbstractObject::setKey(): Argument #1 ($key) must be of type string, null given, called in /var/www/html/vendor/pimcore/data-importer/src/Mapping/DataTarget/Direct.php on line 119" ["class" => "Pimcore\Bundle\DataImporterBundle\Messenger\DataImporterMessage","retryCount" => 3,"delay" => 4000,"error" => "Handling "Pimcore\Bundle\DataImporterBundle\Messenger\DataImporterMessage" failed: Pimcore\Model\DataObject\AbstractObject::setKey(): Argument #1 ($key) must be of type string, null given, called in /var/www/html/vendor/pimcore/data-importer/src/Mapping/DataTarget/Direct.php on line 119","exception" => Symfony\Component\Messenger\Exception\HandlerFailedException^ { …}]

Steps to reproduce

• create import with a mapping that assigns a value to the System Key
• try to import an empty value to this

Not able to reproduce the exact error. I tried with an empty key and got the exception

Exception: DataObject requires key in /var/www/html/dev/pimcore/pimcore/models/DataObject/AbstractObject.php:688

Also, the importer didn't get stuck because of the exception. The next element was imported.
