Rxjs Observable Issue

[forvy]

With the current library on line 3 of ngx-breadcrumbs.es5.js:

import { Observable as Observable$1 } from 'rxjs/Observable';
giving error:

ERROR TypeError: rxjs_Observable__WEBPACK_IMPORTED_MODULE_2__.Observable.of is not a function
at McBreadcrumbsService.push../node_modules/ngx-breadcrumbs/ngx-breadcrumbs/ngx-breadcrumbs.es5.js.McBreadcrumbsService._resolveCrumbs

and breadcrumb not shown.

But after changing into:
import { Observable as Observable$1 } from 'rxjs';

It's doing good again.
