我已经在木兰cms上实现了代码，任务是获取另一种隐藏形式（来自Marketo）的形式值。该代码在Magnolia社区版中可以正常工作，但在生产环境中则不能。请帮助代码。怎么了？
木兰Webform的HTML：

var customForm = document.querySelector("#commandDEsk2_form"),
customFormButton = customForm.querySelector("input[type='button']");
if (customFormButton!= null) {
customFormButton.addEventListener("click",function(customFormSubmitEvent){
customFormSubmitEvent.preventDefault();
customFormButton.disabled = true;
MktoForms2.whenReady(function(mktoForm) {
mktoForm.addHiddenFields({
"FirstName": customForm.querySelector("#mwf23e481e7bdc0").value,
"LastName": customForm.querySelector("#mwf08d9bc1fbf81").value
});
mktoForm.submit();
});
});
}
</script>
错误：
未捕获的TypeError：无法读取null的属性'querySelector'
