React Google Maps has issues with "loading" state when using StandaloneSearchBox component

<p>I have a page in my React JS page that I'm trying to allow companies to register with my site and add their location so other companies can come rent, buy, etc. I also need to add markup if possible. I have put a Google Map on my page, however, I cannot put the search bar (<code>StandaloneSearchBox</code>) on the page because it stays in the "loading" state. This is my code: </p>
<pre class="brush:php;toolbar:false;">import {useState, useEffect} from 'react'
import { GoogleMap, StandaloneSearchBox, LoadScript } from '@react-google-maps/api';
const initialState = {
company: '',
email: '',
password: '',
isMember: true,
}
const Register = () => {
const mapContainerStyle = {
height: "400px",
width: "800px"
}
const center = {
lat: -3.745,
lng: -38.523
};
const [values, setValues] = useState(initialState)
// global state and useNavigate
const handleChange = (e) => {
console.log(e.target)
}
const onSubmit = (e) => {
e.preventDefault()
console.log(e.target)
}
const handleLoad = ref => this.searchBox = ref;
const handlePlacesChanged = () => console.log(this.searchBox.getPlaces());
return (

<p>I tried adding more imports, such as from the <code>ScriptLoaded</code> file in the ../api/docs folder, but this caused the entire page to go blank. If I remove the <code>StandaloneSearchBox</code> from the <code>import {} from '@react-google-maps/api'</code> and the <code>LoadScript GoogleMap</code> code, It displays normally on the page, just without the search bar and markup to search for addresses (<code>StandaloneSearchBox</code>)</p>

I think the problem is that there is no library. In order to display the search box, a library is necessary.
const lib = ['places'];Set places to a library that must be added to theLoadScriptcode that contains your API key. The updated code should have fixed the issue:import {useState, useEffect } from 'react' import { GoogleMap, LoadScript, StandaloneSearchBox } from '@react-google-maps/api' const lib = ['places']; const mapContainerStyle = { height: "400px", width: "800px" } const center = { lat: -3.745, lng: -38.523 }; const position = { lat: 37.772, lng: -122.214 } const initialState = { company: '', email: '', password: '', isMember: true, } const Register = () => { const [searchBox, setSearchBox] = useState(null); const handlePlacesChanged = () => console.log(searchBox.getPlaces()); const handleLoad = ref => { setSearchBox(ref); }; const [values, setValues] = useState(initialState) // global state and useNavigate const handleChange = (e) => { console.log(e.target) } const onSubmit = (e) => { e.preventDefault() console.log(e.target) } return ( <body class="page-template-default page page-id-13"> <header class="site-header"> <div class="container"> <h1 class="school-logo-text float-left"><a href="/landing"><strong>Direct</strong> Connection</a></h1> <div class="site-header__util"> </div> </div> </header> <div class="page-banner"> <div class="page-banner__bg-image" style={ { backgroundImage: "url('connection.jpg')" } }></div> <div class="page-banner__content container container--narrow"> <h1 class="page-banner__title">Register</h1> <div class="page-banner__intro"> <p></p> </div> </div> </div> <div class="container container--narrow page-section"> <h2 class="headline headline--tiny">Want to join and connect with companies?
