REST API Support

Documentation here: https://developer.wordpress.org/rest-api/extending-the-rest-api/adding-rest-api-support-for-custom-content-types/#registering-a-custom-taxonomy-with-rest-api-support

I manually added that, but I’m only getting null values in the REST API. This is potentially related to https://wordpress.org/support/topic/php-warning-no-property-of-non-object/
