reactjs - 当用户选择一个选项但随后将其更改为另一个选项时，React 崩溃而不显示错误

Question

当用户选择任何选项时，我的代码正在工作。
但是，当他们选择“现在”选项，然后改变主意并选择“特定”选项时，React 崩溃而不显示错误 - 它只是显示一个白屏。
This problem doesn't occur when the options are selected the other way round - when 'specific' is selected and the user changes their mind and selects 'now'.
When 'specific' is selected a new input is rendered.
代码的简化版本如下:

render() {

let startSelling = values.tickets.map((e,i) => {
    if(e.startSelling == 'specific'){
        return(
                <div>                 
                    <DatePicker
                        className="datePicker"
                        timeIntervals={15}
                        onChange={event => this.props.setSpecificTime(event, i, 'startSellingTime', values)}
                        selected={values.tickets[i].startSellingTime}
                        placeholderText='Select Date And Time'
                        showTimeSelect
                        dateFormat="Pp"
                        />
                </div>
        )
    }else{return <div></div>}
})


return (
    <>

        {this.state.tickets.map((e, i) => {
            return (
            <div>
                <div>       
                    <select
                        value={values.tickets[i].startSelling}
                        onChange={event => this.props.changeSellingTimes(event, i, 'startSelling', 'startSellingTime', values)}
                    >
                        <option value='' disabled>Start Selling Tickets</option>
                        <option value="now">Now</option>
                        <option value="specific">Specific Date and Time</option>
                        {i===1 ? <option value="whenPreviousSoldOut">When {values.tickets[0].ticketType} Is Sold Out</option>:<option value="whenPreviousSoldOut" disabled={i==0}>When A Previous Ticket Is Sold Out</option>}  
                    </select>
                </div>
                {startSelling[i]}
        </div>
            )
            
        })}

    </>

)

}
我哪里错了？

找到了。选择“现在”将日期保存为状态中的时刻对象。 Datepicker 在尝试读取它时导致 react 崩溃。
