Google places api Google Places Api autocomplete不返回任何德国邮政编码（地址\u组件）

我试图让GooglePlacesAPI正常工作。 我的问题是我在德国没有邮政编码

Iam使用地址组件并检查所有类型（路线、行政区、级别、邮政编码等）是否有邮政编码，但没有？我需要从别的地方取拉链吗？地理位置

我做错了什么

 function initAutocomplete() {
    address1Field = document.querySelector("#txtTest");
    address2Field = document.querySelector("#hiddenStartTown");
    postalField = document.querySelector("#hiddenStartZip");
    // Create the autocomplete object, restricting the search predictions to
    // addresses in the US and Canada.
    autocomplete = new google.maps.places.Autocomplete(address1Field, {
        componentRestrictions: { country: ["de"] },
        fields: ["address_components", "geometry"],
        types: ["address"], 
    });
    address1Field.focus();
    // When the user selects an address from the drop-down, populate the
    // address fields in the form.
   autocomplete.addListener("place_changed", fillInAddress);

}

function fillInAddress() {
    // Get the place details from the autocomplete object.
    const place = autocomplete.getPlace();
    debugger;
    let address1 = "";
    let postcode = "";

    // Get each component of the address from the place details,
    // and then fill-in the corresponding field on the form.
    // place.address_components are google.maps.GeocoderAddressComponent objects
    // which are documented at http://goo.gle/3l5i5Mr
    for (const component of place.address_components) {
        const componentType = component.types[0];
        
        switch (componentType) {
            case "street_number": {
                address1 = `${component.long_name} ${address1}`;
                break;
            }

            case "route": {
                address1 += component.short_name;
                break;
            }

            case "postal_code": {
                postcode = `${component.long_name}${postcode}`;
                break;
            }
