GET http://localhost:3000/api/users/:userId 400 (Bad Request) ? Axios React - node.js

Question

I trying to display data on the client-side of my react application. when sending a get request for single user by id on my server-side I get a 200 ok status and the user information. But when trying to make an axios call on the client-side i get 400 status error. I believe it is how I use req.params in the server-side get request. how can I refactor the GET request so that I can get the response on the client-side.
Controller
router.get("/:userId", (req, res) => {
const { userId } = req.params;
if(!userId){
return res.status(400).json({message: "user id not found"})
}
if(!ObjectId.isValid(userId)){
return res.status(400).json({ message: "userId not valid"})
}
User.findById(userId,(err, user) => {
if(err) {
res.status(500);
console.log("errr 500")
} else {
if(!user)
res.status(400).json({message:"user not found"});
res.status(200).json({"user" : user})
}
})
})

try adding "proxy":"http://localhost:5000/" in the package.json in react
then use :
axios.get(`/api/users/${userId}`)...
