我正在构建一个react-native应用程序，现在我正在尝试使用我存储的JWT显示我的用户名，所以它在我的代码中看起来像这样：

import { StyleSheet, Text, TouchableOpacity, View } from 'react-native'
import React, { useState } from 'react'
import firebase from '../../firebase';
import { auth } from '../../firebase'
import { signOut } from 'firebase/auth'
import { useEffect } from 'react';
import { useNavigation } from '@react-navigation/native'
import * as SecureStore from 'expo-secure-store';
import { globalStyles } from '../../styles/global'


const SearchScreen = () => {

    const [user, setUser] = useState(null);
    

    // Get the current user's ID token
    const getCurrentUser = async (key) => {
      const idToken = await SecureStore.getItemAsync(key);
      // Decode the ID token to get user information
      const decodedToken = await auth.verifyIdToken(idToken);
      console.log("here is the decoded one :",decodedToken)
      // Set the user's information to the state
      setUser(decodedToken);
    };

    getCurrentUser('jwt');

我确实在根目录下的“firebase.js”文件中设置了我的firebase：

import { getAuth } from "firebase/auth";
import firebase from 'firebase/compat';

const firebaseConfig = {
// private infos & shit you know
};

let app;
if (firebase.apps.length === 0) {
    app = firebase.initializeApp(firebaseConfig);
} else {
    app = firebase.app()
}

const auth = getAuth();

export { auth };

所以在这里我试图弄清楚为什么我会得到这个错误：
WARN可能未处理的Promise拒绝（id：1）：TypeError：undefined不是函数
