User cancelled the dialog

I am getting this error (User cancelled the dialog) when I try the simple code as the example in the Ionic Framework.

this.health.isAvailable()
.then((available:boolean) => {
  console.log(available);
  this.health.requestAuthorization([
    'distance', 'nutrition',  //read and write permissions
    {
      read: ['steps'],       //read only permission
      write: ['height', 'weight']  //write only permission
    }
  ])
  .then(res => console.log(res))
  .catch(e => console.log(e));
})
.catch(e => console.log(e));
