In my schema.graphqls file I've created this Query
type Query {
getLinkedProductsByGroups(groups: [String]): [LinkedProductsByGroup] @resolver(class: "Vendor\\ProductDisplay\\Model\\Resolver\\LinkedProductsByGroups")
}
type LinkedProductsByGroup {
group: String
products: [ProductInterface]
}
I've created my resolver

{

$this->productRepository = $productRepository;
}
public function resolve(Field $field, $context, ResolveInfo $info, array $value = null, array $args = null)
{
$result = [];
$groups = $args['groups'];
foreach ($groups as $group) {
$resultItem = [];
$resultItem['group'] = $group;
$resultItem['products'] = [];
//fetch related products
$linkedProductIds = $this->linkedProductsLocator->getLinkedProductIdsByGroup($group);
$scb = $this->searchCriteriaBuilderFactory->create();
$scb->addFilter('entity_id', $linkedProductIds, 'in');
$searchResults = $this->productRepository->getList($scb->create());
if ($searchResults->getTotalCount() > 0) {
foreach ($searchResults->getItems() as $item) {
$data = $item->toArray();
$data['model'] = 'product';
$resultItem['products'][] = $data;

}
$result[] = $resultItem;
}
return $result;
}
}
This pretty much works but I have a problem fetching composite fields like price or small_image.
When I run my query without them everything is fine.
But with them I get this error
query {
getLinkedProductsByGroups(groups: ["001021", "001107"]) {
group
products {
name
sku
small_image {
url
}
}
}
}
This error comes up

Of course I can't use the price / image fields directly because the ProductInterface type must have a sub-selection for them. But the toArray() and the getData() functions don't give the result as expected. So how do I make it convert the fields properly from the ProductInterface defined in the PHP classes, to the ProductInterface defined in GraphQl so that the result is correct?
