Unfortunately, I am unable to transmit a cookie using the res.cookie method in Express

After setting up the route to send a JWT with a cookie, I'm unable to see it in my browser.

Here's the code for the route:

router.post('/signup', async (req, res) => {
    const { email, password } = req.body
    try {
        const user = await User.create({ email, password })
        const token = createToken(user._id)
        res.status(201).cookie('jwt', token, { httpOnly: true, maxAge: maxAge * 1000 })
    } catch (err) {
        const errors = handleErrors(err)
        res.json({ errors })
    }
})

Despite confirming that the server is functioning correctly and that the token size is under 4kb, the 'jwt' cookie does not appear in the Chrome application tab.

The express version being used is 4.17.1.

Looking at this helpful answer, it seems that adding

credentials: 'include'

to your request could potentially resolve the issue with cookies not being set.
