getting invalid xml error on the magento plugin

[shipnoob]

Hi.

I'm new to ShipStation.  Just set up magento 2 integration.  the test connection works fine.  When i try to import orders i get this error: An error occurred attempting to update orders: Invalid XML. Error: 'Data at the root level is invalid. Line 1, position 1.' We received: 'An error has happened during application run. See exception log for details. '

Magento 2.4.2-p1

The actual error from the log:

[2023-05-17 21:48:50] main.CRITICAL: TypeError: Argument 2 passed to Auctane\Api\Model\Action\Export::addXmlElement() must be of the type string, null given, called in /home/website/public_html/website.com/vendor/auctane/api/Model/Action/Export.php on line 360 and defined in /home/website/public_html/website.com/vendor/auctane/api/Model/Action/Export.php:314

Is anyone familiar with this or have any suggestions?  I'm afraid that without Magento integration ShipStation really isn't going to be useful for us.

Thanks for any insights.
