The input_type attribute of a product EAV attribute specifies the type of input field that will be used to enter the value of the attribute in the admin panel. The textarea input type is used for WYSIWYG fields. If the input_type attribute is not set to textarea, then the attribute will not appear as WYSIWYG in the admin panel.
To fix this, the developer should set the input_type attribute to textarea.

The developer can extend the existing CartltemPrices GraphQL schema to include a custom base_price field by adding the following code to the module's etc/schema.graphqls file:
extend type CartltemPrices { base_price: Money! @doc(description: "The base price of the cart item") } This code adds a new field called base_price to the CartltemPrices type and specifies that it is of type Money and it is not nullable. The @doc directive adds a description for the field that will be shown in the schema documentation. The developer also needs to create a custom resolver class for the base_price field and declare it in the di.xml file of the module. Verified Reference: [Magento 2.4 DevDocs] [Magento Stack Exchange]
