NuxtJs - Cannot read property 'headers' of undefined - authentication

Question

I'm a newbie in NuxtJs. I'm trying to implement an external API Call with axios which I get token and store it on cookie. Everything works well in development. But when I try to run npm run generate it gives me errors that I don't know what to do.
When I delete nuxtSeverInit, npm run generate runs smoothly. And after some research, i think that nuxtServerInit that I'm using shouldn't be used. Can anyone please tell me how to make it work.
This is the first project in a new company, so I'm trying to prove myself. Please help me with it. Will you.

This is store/index.js file
import Vuex from 'vuex'
var cookieparser = require('cookieparser')
const createStore = () => {
return new Vuex.Store({
state: {
auth: null,
},
mutations: {
update (state, data) {
state.auth = data
}
},
actions: {
nuxtServerInit ({ commit }, { req }) {
let accessToken = null
if (req.headers.cookie) {
var parsed = cookieparser.parse(req.headers.cookie)
if(parsed){
accessToken = parsed.auth
}
}
commit('update', accessToken)
},
}
})
}
export default createStore
middleware/authenticated.js file
export default function ({ store, redirect }) {
// If the user is not authenticated
if (!store.state.auth) {
return redirect('/login')
}
}
middleware/notAuthenticated.js file
export default function ({ store, redirect }) {
// If the user is authenticated redirect to home page
if (store.state.auth) {
return redirect('/app/dashboard')
}
}
login.vue file
validateBeforeSubmit() {
this.$validator.validateAll().then((result) => {
if (result) {
this.button_title = 'One moment ...';
let submitted_user_data = {
'username': this.emailAddress,
'client_id': this.user_uuid,
'password': this.password,
}
MerchantServices.do_user_login(submitted_user_data)
.then(response => {
let access_token = response.data.access_token;
this.postLogin(access_token);
})
.catch(error => {
this.$refs.invalid_credentials.open();
this.button_title = 'Sign in'
});
return;
}
});
},
postLogin: function(access_token_val) {
if(access_token_val != ''){
setTimeout(() => {
const auth = {
accessToken: access_token_val
}
this.$store.commit('update', auth)
Cookie.set('auth', auth)
this.$refs.invalid_credentials.open();
this.button_title = 'Sign in'
this.$router.push('/app/dashboard')
}, 1000)
}else{
alert('hello')
}
},
and the last user login api call which also returns the token.
do_user_login(user){
var user_details = 'username='+user.username+'&client_id='+ user.client_id +'&grant_type=password&password='+user.password+''
return axios.post('myapiurl', user_details )
.then(response => {
return response;
});
},

Acording to Nuxt Docs req is not available on nuxt generate.
You should use nuxt build and than nuxt start after that.
