Module development and code questions

This part of my custom form depends on ajax to conditionally show additional fields. It is working.

Hey guys,

I've been having trouble accessing certain fields in an exposed filter.

I have a content type where I insert 3 prices for different types of products.
Some products will have all 3 prices added some just 2 or 1.

All prices are entered based on one currency (EURO).
However, Using twig I have to display one of the prices in $USD, lets call it price 3.

Hi,

I have this sample data and this is just a part of data but it is swagger which is a JSON.

a:14:{s:7:"swagger";s:3:"2.0";s:4:"info";a:6:{s:10:"x-ibm-name";s:22:"test-summary";s:5:"title";s:28:"test Summaries for test";s:7:"version";s:5:"1.0.0";s:11:"description";s:84:"Account Information, retrieve account test and statuses for the test.";s:7:"contact";a:2:

This data is extracted as string on the variable "apiSwagger"

$apiSwagger = $apiNode->api_swagger->value;

Using Drupal 10:

Is this way below (to delete all content for a content type) reliable (instead of using the loadMultiple method)?

\Drupal::database()->delete('node')
->condition('type', "mycontenttype")
->execute();

Created a custom webform product module that includes a composite field for stock settings. After submitting the form, what is the proper way to update the stock value in the backend?

Hello,

I like to make a POST request to add an entity. I was able to do it in Postman. Now I am trying to do the same in VS Studio, but I am getting the error "The website encountered an unexpected error. Please try again later.". 

I created the route in the module's routing.yml that points to a method of the Controller for an HTTP POST request. 

In Postman, I was able to make a POST request as follows and was able to add the entity just fine.
