UseMutation and UseQuery data is undefined in first load

[chechoreyes]

Friends, I have this:

    const reservesStatisticsData = useMutation(getAllStatisticsBetweenDates, {
        cacheTime: 1000 * 60 * 60,
        onSuccess: (data) => {
            setDataReserves(data[0]);
        },
    });

I'm used React|Vite|TypeScript but, in the first load the page crashed and the error is because data is undefined, can please help me?

Regards,
