Angular4 Error trying to diff '[object Object]'

Question

I\'m trying to display some info in the dom but I get this error:

Error: Error trying to diff \'[object Object]\'

What Im trying to

Answer 1

If you want to have price as an array, then you have push the object in prices array.

ngOnInit(){
  this.surbtcService.getPricess()
  .subscribe(
    data => this.prices.push(data.ticker);
  );
}

OR, you can just directly access the object properties by assigning data.ticker to prices.

private prices = new SurbtcMarketView();

constructor(private surbtcService: SurbtcService) {

}
ngOnInit(){
   this.surbtcService.getPricess()
        .subscribe(data =>{
            this.prices = data.ticker;
        });
}

HTML:

  {{item}}

UPDATE:

See the Plnkr demo, I have resolved the issue that was causing error in parsing the json response.
