Current behavior

TypeError: Cannot read property 'indexOf' of undefined

ngsw-worker.js:386

this.config.urls.indexOf(url)

Expected behavior

Should be able to bypass...

(this.config.urls || "").indexOf(url)

Minimal reproduction of the problem with instructions

Unable to fulfill "urls" attribute

What is the motivation / use case for changing the behavior?

To allow the worker to function without having "urls" attribute

Environment

Angular 5.1.0

Browser:
ALL

Can anybody review the code changes uploaded. Thanks.

AFAICT, config.urls can never be undefined, since this field is auto-generated. Having an asset group with no URLs is invalid anyway.
