Cannot read property 'id' of undefined

During development mode lightbox works perfectly fine. But during --prod it gives the error:

Cannot read property 'id' of undefined

I tried various ways to solve it, but could not resolve.

Please look at my code below which opens the lightbox:

open_lightBox(index: number, imageUrl: string) {
this._albums = [];
const album = {
src: imageUrl
};
this._albums.push(album);
this._lightbox.open(this._albums, index);
}
I'm displaying one image at a time, since this is my requirement and that's why I'm clearing the albums object at the start of the method. I'm using latest version of Angular Cli
