This is happening because your are reading the property of something which is undefined.发生这种情况是因为您正在读取未定义内容的属性。 And in your case it is data property in error(in catch block mostly).You can use optional chaining operator to avoid it.在您的情况下，它是错误的data属性（主要在 catch 块中）。您可以使用optional chaining operator来避免它。 I have updated the code.我已经更新了代码。
