Hi,
I have noticed this issue today after trying to display the "Quantity" attribute in the product page

• go to product attribute -> select Quantity one -> Storefront Properties -> Change Visible on Catalog Pages on Storefront to Yes

I still don't know why this happen

Regards,

[saravananvelu]

@magento-engcom-team I am also facing the same issue after changing the Quantity attribute settings.

To reproduce the issue. Please follow the below steps,

Product attribute grid -> select Quantity attribute-> Storefront Properties -> Change Visible on Catalog Pages on Storefront to Yes

[p-makowski]

I confirm that there is an issue with quantity_and_stock_status (Qty) system attribute.
If somebody/admin changes it to be visible on frontend the following happens:

$value in \Magento\Eav\Model\Entity\Attribute\Frontend\AbstractFrontend::getValue is an array (with 2 elements afair: stock and qty). $value is a parameter in $this->getOption($value) and later in $source->getOptionText($optionId);.
Unfortunately \Magento\Eav\Model\Entity\Attribute\Source\AbstractSource::getOptionText($value) is checking the following condition if (isset($options[$value])) {. Array keys can only be scalar, but $value is an array.

W'd like to re-open this.

I could reproduce this with an attribute with custom backend model. Some more info here ... https://magento.stackexchange.com/questions/246201/custom-backend-model-for-multiselect-attributes-causes-exception

Attribute setup:

public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context)
{
    $eavSetup = $this->eavSetupFactory->create();
    $eavSetup->addAttribute(
        Product::ENTITY,
        Helper::ATTRIBUTE_CODE,
        [
            'group' => 'General',
            'type' => 'varchar',
            'label' => 'Label',
            'input' => 'multiselect',
            'source' => 'Vendor\Module\Model\Attribute\Source\Country',
            'backend' => 'Vendor\Module\Model\Attribute\Backend\Country',
            'required' => false,
            'sort_order' => 100,
            'global' => ScopedAttributeInterface::SCOPE_WEBSITE,
        ]
    );
}

Backend model can also be Magento\Eav\Model\Entity\Attribute\Backend\ArrayBackend ...

I have the same problem, this could be a fix (at least the detail page shows again):

        if (false === is_null($value) && false === is_array($value) && isset($options) && isset($options[$value])) {
            return $options[$value];
        }
