Ionic - can't push object with a variable key

I am trying to create an array of phone numbers to use with the ionic native SMS package. It is fairly simple code:

 let array;
 let promises_array = [];
  this.storage.get('username').then((val) => {
    console.log('in storage');
    this.follow = this.af.list('/profiles/stylists/' + val + "/followers");
    this.subscription = this.follow.subscribe(items => items.forEach(item => {
      promises_array.push(new Promise((resolve, reject) => {
        console.log(JSON.stringify(item) + " item item item");
        let arr = Object.keys(item);
        console.log(item[arr[0]] + "    type followers");
        array.push(item[arr[0]]);    ;
        resolve();
      }))
    }));

    Promise.all(promises_array).then(() => {
      let month1 = date.getUTCMonth;
      let date1 = date.getUTCDate;


        this.sms.send(array, val + " just opened up a spot at " + time + " on " + month1 + " " + date1 + "!")
          .catch(e => { console.log(JSON.stringify(e))});
    })
   boool = false;
 })

The error I get (it is a runtime error that appears in the app) - 

Uncaught (in promise): TypeError undefined is not an object (evaluating 'array_1.push')

I have confirmed that array_1.push corresponds to the line:

array.push(item[arr[0]]);

It is saying that item[arr[0]] is undefined, but the console output is:

[10:54:49]  console.log: in storage 
[10:54:49]  console.log: {"V":"7818646634"} item item item 
[10:54:49]  console.log: 7818646634 type followers 
[10:54:52]  console.log: "Message cancelled."

The third line shows that it recognizes what item[arr[0]] is, it just thinks its undefined when it goes to push it. Any help would be great, thanks.

You are not defining the array variable as an array, so it doesn't know it can be pushed to.

let array;

you should do:

let array = [];
