I have issue in form

I have issue in js code that I want to add predictive text inside input field from Google's Locations API

The code is
let currentStep = 0;

function initAutocomplete() {
const input = document.getElementById("address");
const autocomplete = new google.maps.places.Autocomplete(input, {
types: ["address"],
strictBounds: true
});

autocomplete.addListener("place_changed", function() {
    const place = autocomplete.getPlace();

    const desiredCities = ["Washington, DC"];
    const desiredZipCodes = [];
    const desiredCounties = [];
    const desiredStates = ["DC"];

    let isState = true;
    let isCity = true;
    let isZipCode = true;
    let isCounty = true;

    let cityName = "";
    let countyName = "";
    let stateName = "";

    place.address_components.forEach(component => {
        if (component.types.includes("locality")) {
            cityName = component.long_name;
        }

        if (desiredZipCodes.length) {
            if (component.types.includes("postal_code")) {
                isZipCode = desiredZipCodes.includes(component.short_name);
            }
        }

        if (component.types.includes("administrative_area_level_2")) {
            countyName = component.long_name;
        }

        if (component.types.includes("administrative_area_level_1")) {
            stateName = component.short_name;
            if (desiredStates.length) {
                isState = desiredStates.includes(stateName);
            }
        }
    });

    if (cityName && stateName && desiredCities.length) {
        const cityStateCombo = `${cityName}, ${stateName}`;
        isCity = desiredCities.includes(cityStateCombo);
    }

    if (countyName && stateName && desiredCounties.length) {
        const countyStateCombo = `${countyName}, ${stateName}`;
        isCounty = desiredCounties.includes(countyStateCombo);
    }

    if (!isDesiredLocation) {
        showErrorMessage("address-error", "We are not interested in this area.");
    } else {
        hideErrorMessage("address-error");
        changeStep(1);
    }
});



document.getElementById('address').addEventListener('input', async function() {
    const query = this.value;
    const datalist = document.getElementById('address-suggestions');
    datalist.innerHTML = ''; // Clear existing options

    if (query.length < 3) return; // Minimum 3 characters for suggestions

    try {
        const response = await fetch(`https://maps.googleapis.com/maps/api/place/autocomplete/json?input=${encodeURIComponent(query)}&key=YOUR_API_KEY`);
