NextJS - Typescript error when building it

Hi, when I try to run "npm run build" in my nextjs (typescript) project I receive the error from

import { SessionContextProvider } from '@supabase/auth-helpers-react';

import { SessionContextProvider } from '@supabase/auth-helpers-react';

that Property 'initialSession' does not exist on type '{}'. Can somebody help me with solving this? Thanks

<SessionContextProvider
      supabaseClient={supabaseClient}
      initialSession={pageProps.initialSession}
    >

<SessionContextProvider
      supabaseClient={supabaseClient}
      initialSession={pageProps.initialSession}
