Import/export not working for product entity extension

I have done a product entity extension with OneToOneAssociation. It was to add a new short description field. I was able to save the field when editing and adding products from admin. The issue is I am not able to import or export the contents of the new fields using shopware import/export in settings. I mapped the field using “shortDescription.translations.DEFAULT.shortDescriptionValue”.  I am wondering if there is anything I should add in the code for this to work.

 

public function extendFields(FieldCollection $collection): void
    {
        $collection->add(
            (new OneToOneAssociationField(
                'shortDescription',
                'id',
                'product_id',
                ShortDescriptionDefinition::class, false))->addFlags(new Inherited())
        );
    }

 

Hi, I would also like to add a teaser description field to the product, could you share or give me pointers about how to add this? I have create a Struct/CustomProductExtension.php with the following:

class CustomProductStruct extends Struct
{
    /**
     * @var string|null
     */
    protected $teaserDescription;

    public function getTeaserDescription(): ?string
    {
        return $this->teaserDescription;
    }

    public function setTeaserDescription(?string $teaserDescription): void
    {
        $this->teaserDescription = $teaserDescription;
    }
}

and then added in my Extension/Content/Product/CustomProductExtension.php 

class CustomProductExtension extends EntityExtension
{
    public function extendFields(FieldCollection $collection): void
    {
        $collection->add(
            (new OneToOneAssociationField(
                'teaserDescription',
                'id',
                'product_id',
                CustomProductStruct::class, false))->addFlags(new Inherited())
        );
    }

    public function getDefinitionClass(): string
    {
        return ProductDefinition::class;
    }
}

 

add overrode the template by adding to my Resources/app/administration/src/extension/sw-product-detail-base/sw-product-detail-base.html.twig

{% block sw_product_detail_base_basic_info_card %}
    
        {% block sw_product_detail_base_basic_info_teaser_form %}
            
            
        {% endblock %}
        {% block sw_product_detail_base_basic_info_form %}
            {% parent %}
        {% endblock %}
    
{% endblock %}

but wondering how to see, edit, add this on my Product page.
