以下错误是react项目的主页在登录过程后出现的，主页变为空白，然后在profilePicUrl图像中出现空属性错误。

return (
  <div className='home-container'>
    // error
    {posts.map((post) => {
      return (
        <div className='card home-card' key={post._id}>
          <h5 style={{ padding: '10px' }}>
            {/* console.log("post data", post); */}
            <img
                className='profilePic'
                // error
                src={post?.author.profilePicUrl}
                alt='Profile Picture'
            />
            <Link
                to={
                  post.author._id !== state._id
                  ? '/profile/' + post.author._id
                  : '/profile'
                }>
              {post.author.fullName}
            </Link>

JavaScript
