how to get the json response back in the front end that I am sending from my backend? : I am sending this from the backend. 
```
return res.status(404).json({ message: "User does not exist" });
```

and handling the error on the frontend within the catch of my axios, but when I log the 'err' I get a network error rather than the message. How do I get the message?

```
.catch(err => {
            
            console.log(err)
}
```
