Cant catch axios error in promise, response works fine - vue.js

Question

I am trying to catch an error whilst the user tries to access a page without an authentication token.
axios.js?v=012beb2f:840 POST http://localhost:3001/api/get-user 422 (Unprocessable Entity)
Uncaught (in promise) AxiosError {message: 'Request failed with status code 422', name: 'AxiosError', code: 'ERR_BAD_REQUEST', config: {…}, request: XMLHttpRequest, …}
router.beforeEach((to, from, next) => {
const store = useUserStore()
if(to.meta.requiresAuth)
{
try
{
const response = axios.post('/api/get-user', {}, {
headers: {
Authorization: `Bearer ${store.user.token}`
}
})
.then(response => {
console.log(response)
next()
})
}
catch(error)
{
console.log(error)
next('/login')
}
}
else
{
next()
}
})
Thats the code that makes the request to the server. If the token is correct it works fine. However incorrect token throws the error mentioned above. I would like it to redirect to /login page if token is incorrect.
This is the code on server side.
router.post('/get-user', signupValidation, (req, res, next) => {
if(
!req.headers.authorization ||
!req.headers.authorization.startsWith('Bearer') ||
!req.headers.authorization.split(' ')[1]
){
return res.status(422).json({
message: "Please provide the token",
});
}
const theToken = req.headers.authorization.split(' ')[1];
const decoded = jwt.verify(theToken, 'the-super-strong-secrect');
db.query('SELECT * FROM users where id=?', decoded.id, function (error, results, fields) {
if (error) throw error;
return res.send({ error: false, data: results[0], message: 'Fetch Successfully.' });
});
});

Change the synchronous try/catch...
try
{
somePromise.then(...)
}
catch(error)
{
console.log(error)
next('/login')
}
...to instead use the catch() provided by the promise:
const headers = { Authorization: `Bearer ${store.user.token}` };
axios.post('/api/get-user', {}, { headers })
.then(response => {
console.log(response)
next()
})
.catch(error => {
console.log(error)
next('/login')
}}
Note, also, that the OP code incorrectly assigned the axios.post promise to an unused variable called "response".
Alternatively, use the synchronous try/catch style with async/await:
router.beforeEach(async (to, from, next) => {
const store = useUserStore()
if(to.meta.requiresAuth)
{
try
{
const headers = { Authorization: `Bearer ${store.user.token}` };
const response = await axios.post('/api/get-user', {}, { headers });
console.log(response);
next();
}
catch(error)
{
console.log(error)
next('/login')
}
}
else
{
next()
}
})
