Magento 2 - Orders with deleted products ProductRepositoryInterface The product that was requested doesn't exist. Verify the product and try again

Question

If I want to print my order using some PDF extension which uses the table from transactions emails, some invoices with deleted products are causing an error. As a result the table will be blank. However some orders with deleted products print just fine. I believe if it was a configurable product, the error occurs. But I might be wrong with that. If I disable the PDF extension and WeltPixel EnhancedEmail it prints just fine.

There is probably an error in my code, do you have an idea how I could fix it?

The error:

main.CRITICAL: The product that was requested doesn't exist. Verify the product and try again. {"exception":"[object] (Magento\Framework\Exception\NoSuchEntityException(code: 0): The product that was requested doesn't exist. Verify the product and try again. at /xxx/vendor/magento/module-catalog/Model/ProductRepository.php:290)"} []

Answer 1

You could place $this->_productRepository->get calls in try/catch blocks, so you can capture that exception & let code flow continue

For instance

$configProduct = null;
try {
    $configProduct = $this->_productRepository->get($this->getItem()->getProduct()->getSku());
} catch (\Exception $e){
    ...
}
