WooCommerce API Creating Product Variations not working as expected

[admin]

I am having trouble linking attributes/ attribute terms to a variation when using the

/wp-json/wc/v2/products/<product_id>/variations/batch

rest v2 API endpoint. (<a href="https://woocommerce.github.io/woocommerce-rest-api-docs/?php#batch-update-product-variations" rel="nofollow noreferrer">https://woocommerce.github.io/woocommerce-rest-api-docs/?php#batch-update-product-variations</a>)

How can we get the correct response from the API when creating variations that link to global attributes. (Bottom of code below has that API call and response)

<?php

Below is the relevant portion of

$variations_response

above. For global attribute the ids should NOT be 0; but rather the actual attribute id.

["attributes"]=>
  array(2) {
    [0]=>
    array(3) {
      ["id"]=>
      int(0)
      ["name"]=>
      string(6) "test_1"
      ["option"]=>
      string(1) "c"
    }
    [1]=>
    array(3) {
      ["id"]=>
      int(0)
      ["name"]=>
      string(6) "test_2"
      ["option"]=>
      string(1) "f"
    }
  }["attributes"]=>
  array(2) {
    [0]=>
    array(3) {
      ["id"]=>
      int(0)
      ["name"]=>
      string(6) "test_1"
      ["option"]=>
      string(1) "c"
    }
    [1]=>
    array(3) {
      ["id"]=>
      int(0)
      ["name"]=>
      string(6) "test_2"
      ["option"]=>

    }
  }
