**Uncaught (in promise): Error: Cannot find a differ supporting object '{“created”:… of type string**

and lower down it says this: **NgFor only supports binding to Iterables such as Arrays**

in my .TS file,

```auto
public items:any = [];

ionViewWillLoad() {
    const moredata = this.navParams.get('data');
    console.log('here we go: '+moredata);
    this.items = JSON.stringify(moredata)
  }

```

in my html file:

```auto
<ion-content padding>
    <ion-item text-wrap *ngFor="let item of items">
      <h1>testings</h1>
      <p>{{item | json}}</p> 
    </ion-item>
</ion-content>

```

This is an example of why I keep complaining about `any` abuse. If you give `items` a proper type, your IDE and/or build tools will tell you exactly what is going wrong and where.

Hint: you’re assigning the result of `JSON.stringify` to it, which is a string. As the error message tells you, `ngFor` can’t iterate over strings.

Ok thank, I changed it slightly and now I get: **Cannot find a differ supporting object ‘[object Object]’ of type 'object’**

TS

```auto
items:any = [];

ionViewWillLoad() {
    const moredata = this.navParams.get('data');
    console.log('here we go: '+moredata);
    this.items = moredata
  }

```

html

```auto
<ion-content padding>
    <ion-item text-wrap *ngFor="let item of items">
      <h1>testings</h1>
      <p>{{item | json}}</p> 
    </ion-item>
</ion-content>

```

You totally ignored the entire point of my previous post:

**STOP ABUSING `any`**.

ah, so I changed Items to

```auto
items = [];

```

I now get this error:

**Error: Cannot find a differ supporting object ‘[object Object]’ of type ‘object’. NgFor only supports binding to Iterables such as Arrays.**
