Folder structure is:
-public - "font1.ttf"
-src - app - ui - font.ts

font.ts code is:

import { Rajdhani } from "next/font/google";
import localFont from "next/font/local";

export const rajdhani = Rajdhani({
  weight: ["700"],
  subsets: ["latin"],
});

export const font1 = localFont({
  src: "./font1.ttf",
});

I am geeting this error:
