@finke The code looks OK. I guess that it might be something zone-related, e.g. like the following zone.js issue: Losing zone in RxJS and fetch. I’ll suggest you to check in which zone your code is being executed:
onGetNear() {
// ...
this._dataService.nearbySearch(req).subscribe(res => {
this.places = res;
console.log(Zone.current.name);
console.log(this.places);
});
}
