how fix, recovery problem uid LocalStorage ReactJS/ NodeJs - node.js

Question

I would like to explain my problem of the day.
to put you in context, I'm logging in and I'm on a page like my information or my profile.
I have a funny error, so I'm trying to recover data from. my BDD in order to correctly display the telephone number.
the 1st error is the following on my LIVE server when the page opens I have a 404 error which is displayed
and the second when I make a POSTMAN request
{
code: 'ER_BAD_FIELD_ERROR',
errno: 1054,
sqlMessage: "Unknown column 'undefined' in 'where clause'",
sqlState: '42S22',
index: 0,
sql: 'SELECT * from cartebleuuser where telephone=undefined'
}
I would like to be able to display the correct telephone which corresponds to the UID in my database
How can I fix this issue?
import React, { Component } from 'react';
import axios from 'axios'
class Profile extends Component {
constructor(props) {
super(props);
this.state = {
userProfile: null
};
}
getUserProfile = async (telephone) => {
const res = await axios.get(
`https://joke.fr/api/cartebleuuser${telephone}`
);
this.setState({ userProfile: res.data });
console.log(res.data);
}
componentDidMount() {
const user = localStorage.getItem("authUser");
console.log(user);
if (user) {
const { id, telephone } = JSON.parse(user);
this.getUserProfile(telephone);
}
}
render() {
const { userProfile } = this.state;
return (
<div>
{userProfile ? userProfile.telephone : "No user telephone"}
</div>
)
}
}
export default Profile;
MyRoute on BDD
app.get('/api/cartebleuuser', (req, res) => {
const { telephone } = req.params;
console.log(telephone);
connection.query(`SELECT * from cartebleuuser where telephone=${telephone}`, (err, results)
=> {
if (err) {
console.log(err);
return res.status(500).send('Erreur lors de la récupération des employés');
} else {
console.log(results);
return res.json(results);
}
});
});
BDD schéma.
{
"id": 62,
"telephone": "0202020202",
"uid": "dycjibu96zgmzc0KpGAqxKiUsMu2"
