no response after axios.post() - vue.js

Question

Hey I'm working on a Login system on my vue project and have the problem that there seems to be no response from the backend.
This is the backend function:
auth.post('/login', async function (req, res) {
const { email, password } = req.body;
console.log(req);
if(email !== "" && password !== "") {
const account = await User.findOne({ where: { email: email} });
if (account) {
if (await account.validPassword(password)) {
// Generate an access token
const accessToken = jwt.sign({ id: account.id }, SECRET);
const account_data =
{
'id': account.id,
'firstName': account.firstName,
'lastName': account.lastName,
'email': account.email,
'isAdmin': account.isAdmin
}
res.send({accessToken, account_data});
} else {
res.status(200).json("Username or password incorrect");
}
} else {
res.send('Username or password incorrect');
}
} else {
res.send('Username or password incorrect');
}
})
This is the method were I call the action
methods: {
async loginUser(){
let user = await this.$store.dispatch('loginUser', this.loginInfo);
if(user.error){
alert(user.error)
} else {
alert('Thank you for signing in, ' + user.firstName);
}
},
}
This is the action:
async loginUser({commit}, loginInfo){
console.log(loginInfo)
try{
let response = await axios({
method: 'POST',
url: 'http://localhost:4000/api/auth/login',
data: loginInfo,
headers: {
// Overwrite Axios's automatically set Content-Type
'Content-Type': 'application/json'
}});
let user = response.data;
console.log(user);
commit('SET_CURRENT_USER', user);
} catch (e){
alert(e);
return {e}
}
}
Neither the console.log in the try function or in the catch function is triggered.
