Yes problem with your code is rendering is placed outside of the find one method. Put it inside the braces like.

app.get('/profile/profile/dashboard/update/:id',function (req,res,next) {
           //console.log("hello "+req.params.id);
    Product.findOne({_id: req.params.id}).then(product=>{

        console.log("hello india "+ product);
        res.render('update.ejs',{ product: product });
    });
});

The problem is that you are trying to render the data before the findOne is finished. findOne is asynchronic function and that is why the log works for you.

Move res.render inside the then scope:

Product.findOne({_id: req.params.id}).then(product=>{

        console.log("hello check please "+ product);
        res.render('update.ejs',{ product: product });
    });
