SAPUI5 oData POST 500错误

Question

我试图做一个oData创建复选框按下并获得以下错误。不知道这是前端还是后端ABAP问题，因为在另一个项目中使用了相同的功能。

它在创建部分失败，但奇怪的是仍然通过SiteId，ArticleNumber，VarianceDate &的细节已确认。

// Set CheckBox status, X for true, blank for false 
    onVarianceChecked: function (oEvent) { 
     var oEntry = {}; 

     var bindingContext = oEvent.getSource().getBindingContext(this.MODEL_VIEW); 
     var path = bindingContext.getPath(); 
     var object = bindingContext.getModel("SI").getProperty(path); 

     // Pass in the Header fields 
     oEntry.SiteId = this.SiteId; 
     oEntry.ArticleNumber = object.ArticleNumber; 
     oEntry.VarianceDate = moment(new Date(object.VarianceDate)).format('YYYY-MM-DDTHH:mm:ss'); 

     // Set X or blank 
     if (oEvent.getParameter("selected") === true) { 
      oEntry.Confirmed = "X"; 
     } else { 
      oEntry.Confirmed = ""; 
     } 

     // Do the create 
     var oModel = this.getView().getModel("SI"); 
     oModel.create("/VarianceHeaderSet", oEntry, { 
      success: function() { 
       console.log("Variance confirmed"); 
       MessageToast.show("Variance confirmed", { 
        duration: 1000 
       }); 
      }, 
      error: function (oError) { 
       console.log("Error, variance could not be confirmed"); 
       MessageToast.show("Error, variance could not be confirmed", { 
        duration: 1000 
       }); 
      } 
     }); 
    }

'000000000' 是Edm.DateTime初始值，因此，当你模仿一个DateTime属性不是可空就会失败。

转到SEGW并将属性更改为“可为空”或确保始终在POST中提供正确的日期。
