made a new repo today, trying to fetch from a route handler, but I get a type error on calling .json on the response.

  useEffect(() => {
    fetch('/api/get')
      .then((res) => res.json()) // type error
      .then((data) => {
        const result = apiResponseSchema.parse(data)
        setData(result)
        setLoading(false)
      })
  }, [])

type error:

Property 'json' does not exist on type 'Response'. Did you mean to access the static member 'Response.json' instead?

My ts config hasnt been changed...

{
  "compilerOptions": {
    "target": "es5",
    "lib": ["dom", "dom.iterable", "esnext"],
    "allowJs": true,
    "skipLibCheck": true,
    "strict": true,
    "noEmit": true,
    "esModuleInterop": true,

      }
    ],
    "paths": {

    }
  },
  "include": ["next-env.d.ts", "**/*.ts", "**/*.tsx", ".next/types/**/*.ts"],
  "exclude": ["node_modules"]
}

any ideas, driving me a bit mad..
