What is wrong with this XML snippet?

  • A The extension attribute references the wrong interface, it should have referenced the Magento\Sales\Api\Data\InvoiceInterface.
  • B The extension attribute references the repository instead of the interface it implements (Magento\Sales\Api\InvoiceRepositoryInterface).
  • C The type is wrong, string[] should be replaced with array.
Explanation

Extension attributes must be declared for the extensible API data interface of the entity being extended. For invoices, that interface is Magento\Sales\Api\Data\InvoiceInterface; a repository model is not the invoice data interface. The string[] notation is valid for an array extension attribute.
