Shopify API请求

Question

我正在尝试访问Shopify后端，以使用Vanilla JS更新客户的电子邮件，电话和名称。请求正在成功返回，但实际值未更改。 为我的商店创建了一个自定义应用程序，并遵循了文档以访问Shopify

HTML：

<div class="container with_background">
  <form action="" method="" id="updateCustomerForm" class="page-width">
    
    
    <div class="input-wrapper form-row --100">
      <label for="AddressFirstName">First Name</label>
      <input type="text" name="address[id]" id="customerId" value="{{customer.id}}" autocapitalize="words" disabled style="display:none;">
      <input type="text" name="address[first_name]" id="customerFirstName" value="{{customer.first_name}}" autocapitalize="words">
    </div>  

    <div class="input-wrapper form-row --100">
      <label for="AddressLastName">Last Name</label>
      <input type="text" name="address[Last_name]" id="customerLarstName" value="{{customer.last_name}}" autocapitalize="words">
    </div>
    <div class="input-wrapper form-row --100">
      <label for="AddressEmail">Email Address</label>
      <input type="email" name="address[Email_address]" id="customerEmail" value="{{customer.email}}" autocapitalize="words">
    </div>
    <div class="input-wrapper form-row --100">
      <label for="AddressPhone">Mobile Number</label>
      <input type="tel" name="address[Phone]" id="customerPhone" value="{{customer.phone}}">
    </div>
          <button  type="submit" id="saveCustomerToggle" class="btn btn--logout tablinks">Save</button>  

  </form>
</div>

JS：

document.getElementById("updateCustomerForm").addEventListener("submit", function(e){    
        e.preventDefault();
        e.stopPropagation();
  let custID = document.getElementById("customerId").value  ;
  let custFN = document.getElementById("customerFirstName").value  ;
  let custLN = document.getElementById("customerLarstName").value  ;
  let custEM = document.getElementById("customerEmail").value  ;
  let custPH = document.getElementById("customerPhone").value  ;
  
  
  console.log(custFN);
  
  let  customerdata = {
    "customer": {
      "customer.id": custID,
      "customer.first_name": custFN ,
      "customer.last_name": custLN,
      "customer.email": custEM,
      "customer.phone": custPH,
    }
  };

  console.table(customerdata);

  let formData = new FormData(document.getElementById("updateCustomerForm"));
  console.log(formData);
  const xhr = window.XMLHttpRequest ? new XMLHttpRequest() : new ActiveXObject('Microsoft.XMLHTTP');
  xhr.open('PUT', "https://{api_key}:{api_password}@{store}.myshopify.com/admin/api/2022-04/customers/" + {{customer.id}} +".json", true);
  xhr.setRequestHeader("Content-type", "application/json")
  xhr.send(JSON.stringify(customerdata));
  xhr.onreadystatechange = () => {
    if (xhr.readyState === 4) {
      if (xhr.status === 200) {
        console.log(xhr);
        console.log("1");
        console.log(formData);       
        console.table(customerdata);

      } else {
        console.log(xhr);
        console.log("2");
                        console.log(formData);

      }
    } else {
      console.log(xhr);
      console.log("3");
                      console.log(formData);

    }
  };

知道为什么它返回真实，但对实际值没有采取行动？
