RangeError:来自API的空数据的无效时间值

Question

我正在从DB中获取一个项目对象，然后将其提供给react中的状态数据。我在deliveryDate、requestedDate和intakeDate中遇到了问题。有时这些值在DB中为空，在这种情况下，我得到一个无效的时间值错误。我如何为空日期值编码?

RangeError: Invalid Time Value

export class ViewProject extends Component{
constructor(props){
super(props);
console.log('constructor values', props)
this.state={

});
}
});

lol I was dumb…

这个解决了问题:

deliveryDate: project.deliverDate == null ? new Date() : parseISO(project.deliveryDate),
requestedDate: project.requestedDate == null ? new Date() : parseISO(project.requestedDate),
intakeDate: project.intakeDate == null ? new Date() : parseISO(project.intakeDate),
