The selection of the «Products» value for the «Entity Type» dropdown on the backend «System» → «Export» screen leads to the exception: «Class Magento\Bundle\Model\Product\Attribute\Source\Price\Type does not exist»

The Magento\Bundle\Model\Product\Attribute\Source\Price\Type class is really absent both in the latest development and production (2.0.4) versions:

The failed attempt to instantiate the class is occured here:

github.com

magento/magento2/blob/d447fa6e1/app/code/Magento/Eav/Model/Entity/Attribute/AbstractAttribute.php#L537-L537


$source = $this->_universalFactory->create($this->getSourceModel());

The setup class does not set the source_model (source) property:

github.com

magento/magento2/blob/d447fa6e1/app/code/Magento/Bundle/Setup/InstallData.php#L88


$eavSetup->addAttribute(
    \Magento\Catalog\Model\Product::ENTITY,
    'price_type',
    [
        'type' => 'int',
        'backend' => '',
        'frontend' => '',
        'label' => '',
        'input' => '',
        'class' => '',
        'source' => '',
        'global' => \Magento\Eav\Model\Entity\Attribute\ScopedAttributeInterface::SCOPE_GLOBAL,
        'visible' => true,
        'required' => true,
        'user_defined' => false,
        'default' => '',
        'searchable' => false,
        'filterable' => false,
        'comparable' => false,
        'visible_on_front' => false,
        'used_in_product_listing' => true,

So I suggest that the Magento\Bundle\Model\Product\Attribute\Source\Price\Type values is a legacy from an old Magento 2 version.

How to fix:

UPDATE eav_attribute SET source_model = '' WHERE attribute_code in ('price_type', 'sku_type', 'weight_type');
