Nextjs not showing fetched data from strapi

I am working with Strapi and NextJS 14+ and I have successfully fetched data from strapi with its API but I am not able to fetch data in the NEXTJS application.

Here is my code from

file path => post/[slug]/page.js

const getPost = async (id) => {
  const data = await fetch(`http://127.0.0.1:1337/api/posts?filters[Permalink][$eq]=${id}`);
  const post = await data.json();

  return post;
};


export const generateStaticParams = async () => {
    const data = await fetch("http://127.0.0.1:1337/api/posts")
    // const data = await fetch("http://127.0.0.1:1337/api/posts?filters[Permalink][$eq]=my-first-post")
    const posts = await data.json()
  
    return posts.data.map(post => ({
      params: {
        slug: post.attributes.permalink
      }
      
    }))
  }


  export default async function Home({ params: { slug } }) {

    const post = await getPost(slug)

    
    return (
        <>

        <div id={post.id}></div>
        
        
        <ul>
        {post.data.map(item => (
            <>
            <li key={item.id}>{item.attributes.Title}</li>
            </>
        ))}
        </ul>


        </>
    )
}

MY STRAPI API DATA

Below is my API DATA Generated by Strapi and fetched from Postman

{
    "data": [
        {
            "id": 2,
            "attributes": {
                "Title": "My Second Post",
                "Meta_Description": "Some Description",
                "Content": "Some Text",
                "createdAt": "2023-11-27T14:42:07.787Z",
                "updatedAt": "2023-11-27T14:50:16.707Z",
                "publishedAt": "2023-11-27T14:42:29.807Z",
                "Block_editor": null,
                "Permalink": "my-second-post"
            }
        }
    ],
    "meta": {
        "pagination": {
            "page": 1,
            "pageSize": 25,
            "pageCount": 1,
            "total": 1
        }
    }
}

Also, I have tested the code with https://jsonplaceholder.typicode.com/posts with some changes and its working successfully

NOTE:- I am using Next JS - APP Directory

Hi

i recommend to use console.log () to trace data.

Also i just wanna know why do you use generateStaticParams ?

if you use staticparams, why you created getPost function to fetch data.

Just try to take a look this
