I am working on an ecommerce app using mern stack. I tried deploying it on vercel but for some reason the homepage shows the index js code and no other routes work, neither the api routes nor the react router routes. I am pretty sure there is something wrong in the vercel.json. I didn't find any tutorial on vercel.json Here is the repo link : https://github.com/ishanjarwal/mern-sneaker-store Folder Structure : in the root, there are two folders : api and client. the api folder contains a dist for react's build. the api folder is what I want to be deployed and I don't want a seperate repo with api as the root folder. Please give a solution along with explaination and some resource links to learn more.
