error with web server

it says 'Error: Cannot find module './routes/card'

app.js

const express = require('express');
const bodyParser = require('body-parser');
const cookieParser = require('cookie-parser');

const app = express();

app.use(bodyParser.urlencoded({ extended: false}));
app.use(cookieParser());

app.set('view engine', 'pug');

const mainroute=require('./routes');
const cardroutes=require('./routes/card')

app.use(mainroute);
app.use('/cards', cardroutes);

app.use((req, res, next) => {
  const err = new Error('Not Found');
  err.status = 404;
  next(err);
});

app.use((err, req, res, next) => {
  res.locals.error = err;
  res.status(err.status);
  res.render('error');
});

app.listen(3000, () => {
    console.log('The application is running on localhost:3000!')
});

cards.js

const express = require('express');
const router = express.Router();
const data = require('../../data/flashcardData.json').data;
const cards = data.cards;

router.get('/', (req, res) => {
    res.render('card', { question: cards[0].question, hint: cards[0].hint});
});

module.exports = router;

the cards.js file is store in a folder called card which stored in a folder called routes

Looks like a potential route path issue... sounds like the path maybe './routes/card/cards', but I can't be sure, since I don't know the exact file structure.
