title: 'getServerSideProps Export Error'

Why This Error Occurred

You attempted to statically export your application via output: 'export' or next export, however, one or more of your pages uses getServerSideProps.

It is not possible to use getServerSideProps without a server, so you'll need to use next start when self hosting or deploy to a provider like Vercel.

Possible Ways to Fix It

1. If you'd like to keep your application static, you can use getStaticProps instead of getServerSideProps.

2. If you want to use server-side rendering, update your build command and remove output: 'export' and remove next export. For example, in your package.json:

   --- a/package.json
   +++ b/package.json

   {
     "scripts": {
       "dev": "next dev",

   +    "build": "next build",
       "start": "next start"
     }
   }

   {
     module.exports = {
       reactStrictMode: true,
   -    output: "export",
     }
   }
   

Note:

• Removing export does not mean your entire application is no longer static.
• Pages that use getStaticProps or no lifecycle will still be static!
