JavaScript Express Basics Parameters, Query Strings, and Modularizing Routes Randomize Cards

Solution working only halfway, but the code is the same in both cases..?

I tried to make the 'href' attribute as short as possible. It works when I want to see the answer, but doesn't work the other way around.

If I go back to the question, it brings me to http://localhost:3000/?side=answer instead.

Why?

cards.js

const express = require('express')
const router = express.Router()

const { cards } = require('../data/flashcardsData.json').data

router.get('/:id', (req, res) => {
    const { side } = req.query
    const { id } = req.params
    const text = cards[id][side]
    const { hint } = cards[id]

    const templateData = (side == 'question') ? { id, side, text, hint } : { id, side, text }
    res.render('card', templateData)
})

module.exports = router

card.pug

extends layout.pug

block content
    section#content
        h2= text
        if hint
            p
                i Hint: #{hint}
        if (side==='question')
            //- this gets me to http://localhost:3000/cards/3/?side=answer which is expected
            a(href=`/?side=answer`) Show Answer
        else
            //- this gets me to http://localhost:3000/?side=answer which is not expected
            a(href=`/?side=question`) Show Question
