 * Hi neilgee,
 * This error seem to be coming from the **StarShipIT shipping plugin**, not from
   WooCommerce core. The plugin is failing to retrieve shipping rates from the StarShipIT
   API.
 * Recommended steps:
    1. **Check StarShipIT API credentials** – Verify the API key in the plugin settings
       is still valid
    2. **Check StarShipIT service status** – There may have been an API outage on December
       2nd
    3. **Contact StarShipIT support** – Since this is their plugin, they can investigate
       why the API is returning null instead of rates data
    4. **Check for plugin updates** – See if there’s a newer version of the StarShipIT
       plugin available
 * As a temporary workaround, you could disable the StarShipIT plugin to restore
   cart functionality, then use an alternative shipping method until the issue is
   resolved.
