A white screen appears on the screen because the product is not received as props in PetItem.js.

import React from "react";
import "../PetItems/Items.css";
import { Link } from "react-router-dom";

export default function PetItem({ product }) {
  const { imgURL, name, funding, id } = product; 
  return (
    <div className="product"> 
      <Link to={`/ItemsPage/${id}`}> 
        <img src={imgURL} alt={name} />
        <div className="item-detail first second"> 
          <p className="funding-title"></p>
          <p className="item-name">{name}</p>
          <p className="item-funding">
            <span className="funding">펀딩:</span> {funding}
          </p>
          <p className="FundingPeriod">
            <span className="period">펀딩기간:</span> 
          </p>
        </div>
      </Link>
    </div>
