Ionic 4 wordpress authentication

Good day Expert. Please I have a little worry if someone can help me out. I am using WordPress JWT plugins to authenticate users in my ionic 4 apps, but the issue am having is that when a user try to log in the first time it returns null, with this error message –

https://example.com/wp-json/wc/v3/customers/null?consumer_key=ck_xxxxxxxxxxxxxx&consumer_secret=cs_xxxxxxxxxxxxx.
–HttpErrorResponse {headers: HttpHeaders, status: 404, statusText: “OK”, url: “https://example.com/wp-json/wc/v3/cu…ecret=cs_xxxxxxxxxxx”, ok: false, …}, but the local storage returns the customer data and id with a toast showing login successful. when the user tries it the second time, that’s when the user will be authenticated. But I want user to be authenticated once the login is successful

Don’t know what I have done wrong. This is my code.

login.page.ts


loginForm(){

    this.platform.ready().then(() => {

      if((this.password != '') &&  (this.CFS.validateEmail(this.email))) {

        console.log('Email: ',this.email);

        console.log('Password: ',this.password);
  
        this.auth.loginCustomer(this.email,this.password).then((response) => {

      if(response['token']){

        console.log('Returned Token: ',response['token']);

        console.log('Returned user enamil: ',response['user_email']);

        this.CFS.presentToast('Login successful', 'buttom',2000, 'success');

        this.auth.getUserData(this.email).subscribe((userData) => {

         this.customerData = userData;

          console.log('Customer Data: ', this.customerData);

         let currentUserId = this.customerData[0].id;

         localStorage.setItem('currentUserId', currentUserId);

         let found = localStorage.getItem('currentUserId');

         console.log('local storage id', found);
     
        });
          this.route.navigateByUrl('/home');
      } else {

        this.CFS.presentToast('Invalid username or password', 'buttom',2000,'danger');
      } 

    });

      } else {

        this.CFS.presentToast('Please fill  the form correctly', 'buttom',2000,'danger')

      }

    });

  }

Home.page.ts


   customerId:any;

   customerData: any = {

    avatar_url: 'not found',

  }

  constructor(private CFS: CommonfunctionService, private activatedRoute: ActivatedRoute, private auth: AuthService, private WC: WoocommerceService, private modalPop: ModalController) {

   }
     ngOnInit() {  
    let isUserLoggedIn =  localStorage.getItem('currentUserId');

    this.WC.getUserInfo(isUserLoggedIn).subscribe((data)=>{

      this.customerData = data;

      console.log('user data', this.customerData);

    }); 

    this.WC.getWalletBalance(isUserLoggedIn).subscribe((data) =>{

      this.mybalance = data;

      console.log('All Orders balance by a customer', this.mybalance);

    });
  }

please I need your assistance. Thanks
