Forge application can't fetch google drive file

[Bassem alameddine]

Hello, 
i am creating a forge application where users can click on a button and authenticate through google to fetch there drive files 

the link to authenticate is the following: https://nodejs-production-820f.up.railway.app/auth/google 

the app code is the following

const authenticate = async () => {

        try{

            const ROOT = "https://nodejs-production-820f.up.railway.app"

            const url = `${ROOT}/auth/google`

            const res = await api.fetch(url);

            const data = await res.json();

            if (!data) {

                console.log("no data found");

                setData([]);

            }

            setData(data);

        }

       catch(ex){

        console.log(ex)

       }

    }

but sadly the app is not working and the user is not being redirected to google auth
