Cordova linkedin does not respond any thing back

I have installed the plugin and configured it in the linkedin website

scopes: LinkedInLoginScopes[] = ['r_basicprofile', 'r_emailaddress', 'rw_company_admin', 'w_share'];
linkedinLogin() : void {
    this.linkedin.login(this.scopes, true)
      .then(() => {
        // get connections
        .then(profile => {
          this.userData = {
            username: profile['headline'],
            picture: '', 
            email: '', 
            first_name: profile['firstName'], 
            last_name: profile['lastName'],
            perfil: profile['siteStandardProfileRequest']['url']
        }).catch(e => alert('Erro get connections: ' + e));
      }).catch(e => alert('Erro Login' + e));

when I click on the button(linkedinLogin()) I don’t get any response nor it does through any error. just no action takes place.
