You should get rid of this line in your express function

res.status(200).json("hello from code with himanhsu 12315464968 darling")

You will then have this

import User from "../model/UserSchema.js"
export const getuser = async (req, res) => {
    try {
        let user = await User.find()
        res.json(user)
    } catch (error) {
        res.json({ message: error.message })
    }

}
