An Adobe Commerce developer has added an iframe and included a JavaScript library from an external domain to the website. After that, they found the following error in the console:
Refused to frame [URL] because it violates the Content Security Policy directive.
In order to fix this error, what would be the correct policy ids to add to the csp_whitelist.xml file?
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>
An Adobe Commerce Developer is tasked with creating a custom form which submits its data to a frontend controller They have decided to create an action and have implemented the \Magento\Framework\App\Action\HttpPostActioninterface class, but are not seeing the data being persisted in the database, and an error message is being shown on the frontend after submission.
After debugging and ensuring that the data persistence logic is correct, what may be cause and solution to this?
According to the Magento Stack Exchange answer, form key validation is a security feature that prevents CSRF attacks by checking if the form key in the request matches the one generated by Magento. If the developer does not include the form_key in their custom form, the validation will fail and an error will be shown. Therefore, the developer needs to add the form_key to their requests by using <?= $block->getBlockHtml ('formkey') ?> in their template file.

An Adobe Commerce developer is working on a module to manage custom brand entities and wants to replicate the following SQL query using SearchCriteria:
A)
B)
C)
The following SearchCriteria query will replicate the SQL query:
$searchCriteria = new \Magento\Framework\Api\SearchCriteriaBuilder();
$searchCriteria->addFilter('name', 'Brand 1', 'eq');
$searchCriteria->addFilter('status', 1, 'eq');
$brandCollection = $this->brandRepository->getList($searchCriteria);
The di. xml file of a module attaches two plugins for the class Action.
The around plugin code is:
What would be the plugin execution order?
A)
B)
C)
The plugin execution order is as follows:
PluginA::beforeDispatch()
PluginB::beforeDispatch()
PluginA::aroundDispatch()
The code in the around plugin
PluginB::afterDispatch()
PluginA::afterDispatch()
The aroundDispatch() method is executed in a separate scope, so the code in the around plugin will be executed after the beforeDispatch() methods of both plugins, but before the afterDispatch() methods of both plugins.
Here is a diagram that shows the plugin execution order:
PluginA
beforeDispatch()
aroundDispatch()
afterDispatch()
PluginB
beforeDispatch()
afterDispatch()
An Adobe Commerce developer adds a new extension attribute to add an array of values to the invoices that are fetched through the APIs.
After a while, their technical manager reviews their work and notices something wrong with the extension_attributes. xml file that the developer created in their module:
What is the problem with this xml snippet?
The extension attribute is referencing the repository instead of the interface it implements. The correct XML snippet should be:
XML
<extension_attributes>
group='General' translate='true'> <description>This attribute stores an array of custom values for the invoice.</description> <source_model>Magento\Sales\Api\Data\InvoiceInterface</source_model>
</extension_attributes>
The source_model attribute specifies the interface that the extension attribute is associated with. In this case, the extension attribute is associated with the Magento\Sales\Api\Data\InvoiceInterface interface.
