Does ‘runtimeConfig’ exist in type ‘NuxtConfig’ in Visual Studio Code?

I’m trying to create a Nuxt 3 project based on installation guide: https://nuxt.com/docs/getting-started/installation.
I followed it step by step. But when i want to configure nuxt.config.ts and i paste sample config file from https://nuxt.com/docs/getting-started/configuration:

export default defineNuxtConfig({
  runtimeConfig: {
    // The private keys which are only available server-side
    apiSecret: '123',
    // Keys within public are also exposed client-side
    public: {
      apiBase: '/api'
    }
  }
})

I’m getting a typescript error:

Argument of type '{ runtimeConfig: { apiSecret: string; public: { apiBase: string; }; }; }' is not assignable to parameter of type 'NuxtConfig'.
  Object literal may only specify known properties, and 'runtimeConfig' does not exist in type 'NuxtConfig'.ts(2345)

I’m using node version 16.16.0 and Visual Studio Code is my IDE.
