in edit profile, i am getting req.body is undefined

[sc0rp10n-py]

i added some values in the profile and want to edit them, so i did like in code here https://github.com/hoangvvo/nextjs-mongodb-app/blob/v2/pages/api/user/index.js

const {quote} = req.body;

but i get this error

Cannot destructure property 'baseName' of 'req.body' as it is undefined."

even console.log(req.body) gives undefined.
