Next.js Dynamic Routes and getServersSideProps occur error while export

Actually I am new in Next.js and face such error that I never face before! I am doing my next project where I use getServerSideProps to fetch data. And it was a dynamic route ([id].js) The problem occur when I hit the build command to deploy the tiny project on my hosting.

This is my next [id].js file –

import React from 'react'
import Related from './related';

export default function id(props) {
  return (
    <div>
    <div className="card">
        <div className="card-title">{props.data.title}</div>
        <div className="card-body">{props.data.body}</div>
    </div>
    <Related sendData={props.allData}/>
    </div>
  )
}

export const getServerSideProps =async (ctx)=>{
    const {params} = ctx;
    const res = await fetch(`https://jsonplaceholder.typicode.com/posts/${params.id}`)
    const data = await res.json()

    const allRes = await fetch('https://jsonplaceholder.typicode.com/posts/')
    const allData = await allRes.json();
    return{
        props:{
         data, allData
        }
    }
}

And this is the error –
