Javascript 在React JS'；s州

我在SpringBoot（Java）中有RESTAPI。我正在为我的应用程序使用React JS

下面是我的Product类Java代码，它具有类型为List的productComponents变量：

private String name;
@OneToMany(cascade = {CascadeType.ALL})
@JoinColumn
private List<Product> products;

在React JS中，以下是我的状态：

  this.state = {
     supplier:
       [
         {
         id: 0,
         accountNumber: "Account Number",
         companyName: "Company Name",
         phoneNumber: "Phone Number",
         email: "Email",
         productComponents: [{
                  id: "Component ID",
                  name: "Component Name",
                  unit: "Component Unit",
                  quantity: "quantity",
                  componentCost: "cost",
                  componentPrice: "price",
                  createdAt;
                  status: "Status"
               }],
          },
        ]

当我尝试在React中设置状态时，会出现一个错误，具体来说，当我尝试在React的状态下设置Java中productComponents变量List的哪种类型时，会出现错误

---

这种错误的可能解决方案是什么？

请添加您正在获取的错误。我认为错误在createdAt；

  this.state = {
     supplier:
       [
         {
         id: 0,
         accountNumber: "Account Number",
         companyName: "Company Name",
         phoneNumber: "Phone Number",
         email: "Email",
         productComponents: [{
                  id: "Component ID",
                  name: "Component Name",
                  unit: "Component Unit",
                  quantity: "quantity",
                  componentCost: "cost",
                  componentPrice: "price",
                  createdAt;
                  status: "Status"
               }],
          },
        ]
