Faulty error response from WooCommerce Rest API Coupon Delete

Question

Steps to Reproduce:

1. Create a new coupon (or use the id of an existing one).
2. Delete it with an http request to DELETE /wp-json/wc/v3/coupons/<id> as per the WooCommerce Rest Api Documentation. The resulting response always seems to be

{
  "code": "woocommerce_rest_cannot_delete",
  "message": "The shop_coupon cannot be deleted.",
  "data": {
    "status": 500
  }
}

Even though the checking the coupons status, which is now trash, shows that the deletion was successful.

Did not find any record of this problem posted online. I tracked the problem to the Woo source code.

class-wc-rest-crud-controller.php

$object->delete();
$result = 'trash' === $object->get_status();
...
if ( ! $result ) {
    /* translators: %s: post type */
    return new WP_Error( 'woocommerce_rest_cannot_delete', sprintf( __( 'The %s cannot be deleted.', 'woocommerce' ), $this->post_type ), array( 'status' => 500 ) );
}

The above code looks ok, it’s reasonable that the status of the object should change to trash upon a successful call to $object->delete(); . However, looking closer at the code in WC_Coupon delete()

wp_trash_post( $id );
do_action( 'woocommerce_trash_coupon', $id );

The trashing of the coupon is accomplished with a global function which is independent of the WC_Coupon object that is saved in $object. Therefore the line from above $result = 'trash' === $object->get_status(); will always come back false.
