based on this code,

import { initializeApp } from 'firebase/app';
import { getFirestore } from 'firebase/firestore';
import { collection, addDoc } from 'firebase/firestore';
import jsonData from '/Users/user/mobilegaitapp/app/(tabs)/data/o2-74-9.json'; // Import JSON   data
import * as tf from '@tensorflow/tfjs';
import { fetch, bundleResourceIO } from '@tensorflow/tfjs-react-native';

// Initialize Firebase
const firebaseConfig = {
apiKey: “AIzaSyDVbz-aiY7qqn02fXvkVTvXkVfdB4Na5BU”,
authDomain: “mobile-gait-app-41e79.firebaseapp.com”,

};

const app = initializeApp(firebaseConfig);

// Connect Firestore to your Expo-managed React Native App
const db = getFirestore(app);

export default function App() {

  async function loadModel(){
    console.log("[+] Application started")
    // Wait for tensorflow module to be ready
    await tf.ready();
    console.log("[+] Loading custom mask detection model");

    // Replace model.json and group1-shard.bin with your own custom model
    const modelJson = require("/Users/user/mobilegaitapp/assets/model/model.json");
    const modelWeight = require("/Users/user/mobilegaitapp/assets/model/group1-  shard1of1.bin");

    // Load model
    const model = await tf.loadLayersModel(bundleResourceIO(modelJson, modelWeight));
    console.log("[+] Custom mask detection model loaded");

    }

  loadModel();

  return null;
}

this code is in my index.tsx file when I try to deploy my deep learning model in react native expo go.

i have this error.

Android Bundling failed 4668ms node_modules/expo-router/entry.js (906 modules)
error: node_modules/expo-router/_ctx.android.js: /Users/user/mobilegaitapp/node_modules/expo-router/_ctx.android.js: Expected fromDir to be of type string, got undefined

i try to upgrade the package but still cannot. i do not understand why I cannot run the mobile application.
