LinkedIn doesn't respond

#1

I have installed the linkedin plugin. I’m testing it in a device & I’m not getting any response.This is my code.

// linkedin login
  linkedinLogin() {
    this.linkedin.login(this.scopes, true)
    .then(() => {
        this.isLoggedIn = true;
        this.getSelfData();
    })
    .catch(e => console.log('Error logging in', e));
  }

  // get data from linkedin
  getSelfData() {
    this.linkedin.getRequest('people/~')
        .then(res => {
            this.selfData = res;
            console.log(this.selfData);
            //this.authservices.linkedinAuth(this.selfData);
            this.alertShow(this.selfData)
        })
        .catch(e => console.log(e));
  }

  alertShow(profileData) {
    let alert = this.alertCtrl.create({
      message: profileData
    });
    alert.present();
  }

When I click on the button I don’t get responce.
