[DO NOT MERGE] Failed test

[rpanosSFDC]

This is my attempt to run this example:
https://developer.salesforce.com/docs/component-library/documentation/en/lwc/lwc.unit_testing_using_wire_utility

In recipes so we can convert our two sets wire of tests to the "2.0" version - which is much closer to the modern version AND it is not using the now illegal library "lwc-wire-service-sfdc-mocks"

Unfortunately running :

npm run test:unit productCard

Gives:
● Test suite failed to run

TypeError: Invalid adapterId, it must be extensible.
