The developer can resolve this issue by creating a plugin for the Magento\Catalog\Model\Indexer\Product\Price::executeRow() method. This method is responsible for updating the product price index.

The plugin can be used to add the pricing adjustment from the database to the product price index. Once the product price index is updated, the layered navigation will display the correct price.

Here is an example of a plugin for the executeRow() method:

PHP

class MyPlugin

{

public function executeRow(

\Magento\Catalog\Model\Indexer\Product\Price $subject,

\Magento\Catalog\Model\Product $product,

array $data

) {

$adjustment = $this->getAdjustment($product);

$product->setPrice($product->getPrice() + $adjustment);

}

private function getAdjustment(Product $product)

{

$adjustment = $product->getData('adjustment');

if (!is_numeric($adjustment)) {

return 0;

}

return $adjustment;

}

}

This plugin will add the adjustment data from the product to the product price index. Once the product price index is updated, the layered navigation will display the correct price.

The reason why there are records remaining in the inventory_reservation table is that only reservations no longer needed are removed by the cron job. The inventory_reservation table tracks the quantity of each product in each order and creates a reservation for each product when an order is placed, shipped, cancelled or refunded. The initial reservation has a negative quantity value and the subsequent reservations have positive values. When the order is complete, the sum of all reservations for the product is zero. The cron job removes only those reservations that have a zero sum from the table, leaving behind any reservations that are still needed for incomplete orders.

The developer can add a virtual type for Myvendor\MyModuie\Modei\customPdfupioader specifying the aiiowedExtensions and the maxFiiesize for the constructor, within the module's di.xmi. This way, the developer can reuse the existing file uploader class and customize it for the specific field without modifying the core code.

The next steps to reduce the downtime are to check that the SCD is configured under the build phase and to increase the SCD.THREADS to speed up the build process. The SCD stands for static content deployment, which is the process of generating and deploying static files such as CSS, JS, images, etc. By configuring the SCD under the build phase, the static files are generated before the code is deployed to the production environment, which reduces the downtime during deployment. The SCD.THREADS is a variable that determines how many threads are used for parallel processing during the SCD.By increasing the SCD.THREADS, the developer can improve the performance and efficiency of the SCD process.

The frame-ancestors directive specifies the domains that are allowed to embed the current page in an iframe. The connect-src directive specifies the domains that are allowed to be loaded by the current page through a <script> tag or XMLHttpRequest.

In this case, the developer has added an iframe that embeds a page from an external domain. The Content Security Policy (CSP) is preventing the iframe from being loaded because the domain of the external page is not listed in the frame-ancestors directive.

To fix this error, the developer needs to add the domain of the external page to the frame-ancestors directive. They can do this by adding the following line to the csp_whitelist.xml file:

<frame-ancestors>https://www.example.com</frame-ancestors>
