错误：无效挂钩调用。 | 使用 getStaticProps (Next.js) 中的上下文获取数据的问题

Question

I'm new to react/next and I'm trying to load my post with getStaticProps, the problem is if I use the "useAppContext" or even "useContext(AppContext)"

error - Error: Invalid hook call. Hooks can only be called inside of the body of a function component. This could happen for one of the following reasons:

1. You might have mismatching versions of React and the renderer (such as React DOM)
2. You might be breaking the Rules of Hooks
3. You might have more than one copy of React in the same app

If I use this "useContext" inside of the body of my function component it indeed loads correctly but how could I retrieve the id of the post on my getStaticProps function?

My actual code:

import { GetStaticPaths, GetStaticProps } from 'next';
import { useAppContext } from '../../context/AppContext';

interface PostProps {
  post: {
    field_body: string,
    field_description: string,
    field_posts_tags: string,
    nid: string,
    title: string,
    field_readingtime: string
  }
}

export default function PostTemplate({post}: PostProps) {
  console.log(post);
  return (
    <h2>test</h2>
  )
}

export const getStaticPaths: GetStaticPaths = async() => {
  return {
    paths: [],
    fallback: true
  }
}

export const getStaticProps: GetStaticProps = async () => {
  const value = useAppContext();
  const postNid = value.postNid;
  const post = await fetch(`https://cms.jonasdev.com.br/api/posts/get/${postNid}`)
    .then(response => response.json())
    .then(response => response[0])

  return {
    props: {
      post
    },
    revalidate: 60 * 60 * 24 //24h
  }
}

Since I could not find a way to use context inside of getStaticProps I changed how I handle the get request - now I'm no longer using the post id (postNid) but the slug (eg /using-multiple-deploy-keys) to query the full data of the post. Since I'm no longer using context I was able to use getStaticProps to fetch the data.
