I'm new to OneSignal SDK but I got a similar issue today.
I think the init() function is async and you need to wait to call login().

I fixed it like this:

void OneSignal.init({
  appId,
}).then(() => {
  if (user) {
    void OneSignal.login(user.id)
  } else {
    void OneSignal.logout()
  }
})

You can also use await like:

await OneSignal.init()
await OneSignal.login()

@martin-eq fix worked for me.

  React.useEffect(() => {
    if (typeof window === "undefined") return;

    async function initOneSignal() {
      OneSignal.Debug.setLogLevel("debug");

      await OneSignal.init({
        appId: env.NEXT_PUBLIC_ONESIGNAL_APP_ID,
        allowLocalhostAsSecureOrigin: true,
        safari_web_id: env.NEXT_PUBLIC_ONESIGNAL_SAFARI_WEB_ID
      });
      setIsOneSignalReady(true);
    }
    void initOneSignal();
  }, []);

  const userId = session?.user.id;
  React.useEffect(() => {
    if (!isOneSignalReady) return;
    async function syncOneSignal() {
      if (userId) {
        await OneSignal.login(userId);
      } else {
        await OneSignal.logout();
      }
    }
    void syncOneSignal();
  }, [isOneSignalReady, userId]);

As @martin-eq pointed out, please make sure to await the init() call before calling other OneSignal methods. I'm going to close this issue now but if this issue persists, please comment back/open a new issue with an included example for us to inspect. Thanks
