ISSUE : DOMDocument::createElement(): Argument #2 ($value) must be of type string, Ups\Entity\Shipper given

Hello @Rud5G @thijsw @okj579 @MPiccinato @JREAM

I 'm facing a issue in the shipping class
"DOMDocument::createElement(): Argument #2 ($value) must be of type string, Ups\Entity\Shipper given"
under gabrielbull\ups-api\src\Shipping.php
$shipperNode->appendChild($xml->createElement('ShipperNumber', $shipment->getShipper()->getShipperNumber()))

;

Hi @TuhiranDevbhuti, how are you setting ShipperNumber? It looks like it contains an object instead of a string.
