No provider for InjectionToken proxy.uri!

[Sleeper9]

When I don't set PROXY_URI, it gives me the following message:

ERROR Error: Uncaught (in promise): Error: StaticInjectorError(AppModule)[ExternalService -> InjectionToken proxy.uri]: 
  StaticInjectorError(Platform: core)[ExternalService -> InjectionToken proxy.uri]:

Maybe somehow related to #3 , I suppose it's not mandatory to give PROXY_URL

[sante85]

declare PROXY_URL empty
{provide: PROXY_URI, useValue: ""}

update version 1.8.5
