i’m using React, Node.js(express.js), PostgreSQL. I want to use validation with react-hook-form library. before i use it, i could change date. but i add the code i couldn’t change the date. what is my false? How can i change the data, using react-hook-form library. Thanks for your effort in advance.

the code that i can’t change the date.

import { useState, useEffect, useRef } from "react";
import { useForm } from "react-hook-form";

const [startDate, setStartDate] = useState(formattedDate);

const handleStartDateChange = (e) => {
    setStartDate(e.target.value);
  };


 <input
                type="date"
                id="startDate"
                value={startDate}
                onChange={handleStartDateChange}
                className="form-control"
                
                {...register("startDate", { required: true })}
                dateformat="yyyy-MM-dd"
                style={{
                  width: "100%",
                  maxWidth: "9rem",
                  color: "#212529",
                  fontSize: "16px",
                  fontFamily: "auto",
                }}
                onClick={(e) => e.target.showPicker()}
              />

import { useState, useEffect, useRef } from "react";
import { useForm } from "react-hook-form";
