ternSecureInstrumentation()

create instrumentation.ts in your root directory.

Note

ternSecureInstrumentation() intercept firebase requests to add referer in the header. so firebaseServerApp wont throw auth/refer-empty error.

instrumentation.ts

import { ternSecureInstrumentation } from "@tern-secure/nextjs/server";

export async function register() {
  if (process.env.NEXT_RUNTIME === "nodejs") {
    ternSecureInstrumentation();
  }
}
