Import of select operator breaks when using systemjs and the umd bundle.

[wiredprogrammer]

import { select } from '@ngrx/core/operator/select';

The above import in the log-monitor file of the library causes systemjs when using the umd bundle file to break.

I get this.

 XHR error (404 Not Found) loading http://localhost:42909/vendor/@ngrx/core/bundles/core.umd.js/operator/select

Assuming I understand what is going on with umd then the change would be simple and something along the lines of.

import { select } from '@ngrx/core';

Thanks!
