TS2531: Object is possibly 'null'

I have the following function:-

uploadPhoto() {
var nativeElement: HTMLInputElement = this.fileInput.nativeElement;

this.photoService.upload(this.vehicleId, nativeElement.files[0])
.subscribe(x => console.log(x));
}


however on the nativeElement.files[0], I am getting a typescript error, "Object is possibly 'null'". Anyone can help me solve this issue?

I tried to declare the nativeElement as a null value, however did not manage to succeed.

Thanks for your help and time.
