express-validator giving undefined value when form set to enctype='multipart/form-data'

So I am making this login auth app using basic node.js+express. So when I am taking the values(name, email, etc) from the register page, I am validating the values using express-validator. But, I am getting every value undefined(name, email, etc) when the register page form has enctype='multipart/form-data'. But when I am removing enctype='multipart/form-data', the values are coming just fine!!

So any solution for this? I am just a beginner in Node.js.

(P.S. I need enctype='multipart/form-data' because I am uploading a profileimage while on registration)

(P.S In the code I have removed the middlewares to show the minimal codes for just register.jade and its routes)

I have successfully registered without using enctype='multipart/form-data', but here I can't upload the image.

(P.S. Using multer for file upload)

    form(action="/users/register", method="post" enctype='multipart/form-data')
        .form-group
            label Name
            input.form-control(name="name", type="text", placeholder="Enter Name", class="name")

        .form-group
            label Email
            input.form-control(name="email", type="email", placeholder="Enter Email")

        .form-group
            label Username
            input.form-control(name="username", type="text", placeholder="Enter Username")

        .form-group
            label Password
            input.form-control(name="password", type="password", placeholder="Enter password")
        .form-group
            label Retype Password
            input.form-control(name="password2", type="password", placeholder="Enter password again")

        .form-group
            label Profile Image
            input.form-control(name="profileimage", type="File")

        input.btn.btn-primary(type="submit", name="submit", value="Register")

I expect that I do include enctype='multipart/form-data' for my image upload and that the rest of values does not get set to undefined, because then my express-validator is not working
