Error encountered while running dev in Next.js: Unexpected JSON token 'u' at position 0

Recently, I decided to dive into learning Next.js and sought out resources like the Youtube Video Next.js Crash Course by Traversy Media and the Next.js Official Documentation for guidance.

Following the tutorials, I added the simple code snippet below to my pages/index.js file:

export default function Home()
{
    return <h1>Welcome to my Website</h1>
}

In my package.json file, I included the following scripts:

"scripts": {
"dev": "next dev",
"build": "next build",
"start": "next start"
},

To run the Next.js application, I used the command:

npm run dev

However, upon opening the app in my Chrome Browser, nothing was rendering. The console displayed an error message:

VM117:1 Uncaught SyntaxError: Unexpected token u in JSON at position 0...

Are there any additional steps or settings that need to be configured to successfully launch the Next.js app?

Answer №1

My recommendation is to insert the "scripts":... into a specific location within the existing pre-populated Package.json file, without completely overwriting the entire document.
