Getting count of contacts correct but getting null values for contacts in Ionic 4

import { Contacts } from '@ionic-native/contacts/ngx';

constructor( private contactsPlugin: Contacts ) { }

this.contactsPlugin.find(["displayName", "phoneNumbers","photos"], {multiple: true, hasPhoneNumber: true})
      .then((contacts) => {
        console.log("Length: ", contacts.length);
        for(let i=0; i < contacts.length; i++){
          console.log('... ',contacts[i]);
        }
      }, 
      (error) => {
        console.error("Contacts error: ", error)
      })

I am using,
“cordova-plugin-contacts”: “3.0.1”,
“@ionic-native/contacts”: “^5.0.0”
