貝寶加沙箱 - 付款後發票

我正在整合貝寶加，成功地在我的網站上，除了「支付發票」。貝寶加沙箱 - 付款後發票

這裏的支付牆整合我的JavaScript代碼：

<script src="https://www.paypalobjects.com/webstatic/ppplus/ppplus.min.js" 
type="text/javascript"></script> 

<script type="application/javascript"> 
var ppp = PAYPAL.apps.PPP({ 
"approvalUrl": "<?= $createPaymentArr['links'][1]['href']; ?>", 
"placeholder": "ppplus", 
"language": "de_DE", 
"mode": "sandbox", 
"showPuiOnSandbox": "true", 
"country": "DE" 
}); 
</script>

當我嘗試使用「發票後支付」我得到這個錯誤信息：「很遺憾，我們無法處理您的購買」
