Value Prop Error #912

Question

I'm getting an error saying that the value prop must be an instance of the date. I'm confused because it is???

`import { StyleSheet, Text, View } from 'react-native' import React, {useState} from 'react' import DateTimePicker from '@react-native-community/datetimepicker';

const setup = () => {

//6 AM original time const initialTime = new Date(); initialTime.setHours(9); initialTime.setMinutes(30);

const [time, setTime] = useState(initialTime);

const onChange=(selectedTime)=>{

  const actualTime = selectedTime || initialTime; //in case the user wants the default time,
  setTime(actualTime);
}

return (

<View>
  <Text>Setup</Text>
  <Text>What time do you want to be notified to set your 3 priorities for the day?</Text>
  <DateTimePicker
    testID="dateTimePicker"
    value={time}
    mode="time"
    display="default"
    onChange={onChange}
  />
</View>

) }

export default setup

const styles = StyleSheet.create({})`

Your time state is not a date instance, you should change onChange function because you are setting time state as a native event instead of Date instance. Change the onChange function to be like the following.

  const onChange=(event, selectedTime)=>{
    const actualTime = selectedTime || initialTime; //in case the user wants the default time,
    setTime(actualTime);
  }
