我正在做一个公开的祈祷日志，你也可以在里面添加你最喜欢的圣经经文，一堆一堆。每当我试图添加一个祈祷（或诗句），我得到这个错误：“caught（in promise）TypeError：无法读取undefined的属性（阅读'id'）"。

useEffect(() => {
    getPrayers().then(setPrayer);
    if (object.id) setFormInput(object);
  }, [object]);

  const handleChange = (e) => {
    const { name, value } = e.target;
    setFormInput((prevState) => ({
      ...prevState,
      [name]: value,
    }));
  };

  const handleSubmit = (e) => {
    e.preventDefault();
    if (object.id) {
      updatePrayer(formInput, object.id)
        .then(() => router.push('/prayers'));
    } else {
      const payload = { ...formInput };
      createPrayer(payload).then(setFormInput(initialState));
    }
  };

我尝试将www.example.com更改user.id为user.uid，并将uid更改为user

const createPrayer = (prayerObj, user) => new Promise((resolve, reject) => {
  const prayer = {
    content: prayerObj.content,
    publication_date: prayerObj.pub_date,
    uid: user.id,
  };
  fetch(`${dbUrl}/prayers`, {
    method: 'POST',
    body: JSON.stringify(prayer),
    headers: {
      'Content-Type': 'application/json',
    },
  })
    .then((response) => resolve(response.json()))
    .catch((error) => reject(error));
});
