getting cannot read code of undefined in react nativereanimated

I am trying to create a weekly calendar and has a select date when you tap on the date I want to animate the color change with the help of react native reanimated:3.0.2

Here is my code

    const [selectedDate, setSelectedDate] = useState<Date>(startOfWeek(new Date(), { weekStartsOn: 1 }))    const [week, setWeek] = useState<Date[]>(countWeekDays(startOfWeek(new Date(), { weekStartsOn: 1 })))    const progress = useDerivedValue(() => {        const getIndex = week.findIndex(a => isEqual(a, selectedDate))        return withTiming(getIndex !== -1 ? 1 : 0);    });    const rStyle = useAnimatedStyle(() => {        const backgroundColor = interpolateColor(            progress.value,            [0, 1],            [Config.Theme.COLOR_WHITE, Config.Theme.COLOR_F00A6A]        );        return {            backgroundColor,        };    });// render Iteration    const renderDay = (item: Date) => {        const isSame = isEqual(selectedDate, item)        return (<View key={item.toString()}><Text style={styles.dayText}>{weekDays[item.getDay()]}</Text><TouchableOpacity onPress={() => setSelectedDate(() => item)}><Reanimated.View                        style={[                            styles.dateContainer,                            rStyle,                            // isSame && { backgroundColor: Config.Theme.COLOR_F00A6A },                        ]}><Text style={[                            styles.date,                            isSame && { color: Config.Theme.COLOR_WHITE },                        ]}>{item.getDate()}</Text></Reanimated.View></TouchableOpacity></View>)    }const weekDays = ['Sun', 'Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat'];

Thanks in advance
