Node.js SyntaxError:意外标记''；在<；路径>；在编译ejs时

嘿，堆栈溢出的天才们

*与这个问题有关

我正在创建一个身份证生成器站点，您可以在其中输入您的详细信息以生成身份证和身份证

我使用的是node js

我正在使用ejs模板引擎

使用multer传递图像和req主体

我在听年轻的m.A.在我打字时的汽车自白

问题
我有一个服务器端验证，它应该通过将错误消息和req.body传递到ejs模板来重新呈现页面来显示错误，以显示错误并重新填充输入字段。我已经做了几天了，但不知道错误来自何处

这是错误

在这里，您可以看到我正在使用multer对其进行验证，如果发生错误，它将使用输入和错误再次呈现formDetails页面

这是我的ejs模板文件

    <% if(error){ %>
        <% var Fields = Fields.Fields %>
        <% var error = error.error %>
<% } else { %>
    <% var Fields = { %>
