我想从REST API中获取某个值，并在React native中的文本框中显示。到目前为止，我还没有将其获取到文本框中，其次，它返回此错误

我的源代码是这样的

import { Button, Image, ImageBackground, StyleSheet, Text, TextInput, TouchableOpacity, View } from 'react-native'
import React, { useEffect, useState } from 'react';
import AsyncStorage from '@react-native-async-storage/async-storage';
import { Icon } from '@rneui/base'

const VirtualAccount = () => {

  const [virtualAcc, setvirtualAcc] = useState();
  const [account_number, setAccount_number] = useState("");
  const [bank_name, setBank_name] = useState("");
  

    sayAlert = () =>{
        alert('Text copy button is active');
    }

  
    getVirtualAccount = async () => {
      let token = await AsyncStorage.getItem('token');
      let email = await AsyncStorage.getItem('email');
  
      fetch(
        'https://webserver-migospay.onrender.com/api/user-serv/get-virtual-account/'+email,
        {
          method: 'GET',
          headers: {
            'Content-type': 'application/json',
            Authorization: `Bearer ${token}`,
          },
        },
      )
        .then(response => response.json())
        .then(responseJson => {
          setvirtualAcc(responseJson);
        });
    };

    useEffect(() => {
      //showdata();
      getVirtualAccount();
    });

  return (

我在网上查遍了，还是找不到有价值的东西。或者我到底该怎么做？是不是我遗漏了什么东西？
