Something wrong on Logger service

[sciotta]

I just installed using yeoman command and started using npm start. But in browser nothing shows and I received this error:

ERROR TypeError: Illegal invocation at Logger.webpackJsonp.58.Logger.log (http://localhost:4200/main.bundle.js:1806:18) at Logger.webpackJsonp.58.Logger.debug (http://localhost:4200/main.bundle.js:1767:14) at AppComponent.webpackJsonp.287.AppComponent.ngOnInit (http://localhost:4200/main.bundle.js:846:13) at checkAndUpdateDirectiveInline (http://localhost:4200/vendor.bundle.js:11025:19) at checkAndUpdateNodeInline (http://localhost:4200/vendor.bundle.js:12448:17) at checkAndUpdateNode (http://localhost:4200/vendor.bundle.js:12387:16) at debugCheckAndUpdateNode (http://localhost:4200/vendor.bundle.js:13090:59) at debugCheckDirectivesFn (http://localhost:4200/vendor.bundle.js:13031:13) at Object.eval [as updateDirectives] (ng:///AppModule/AppComponent_Host.ngfactory.js:17:5) at Object.debugUpdateDirectives [as updateDirectives] (http://localhost:4200/vendor.bundle.js:13016:21)

Anybody with the same issue?

Which browser/version are you using?

In app/core/logger.service.ts, try replacing:

 private log(func: Function, level: LogLevel, objects: any[]) {
    if (level <= Logger.level) {
      const log = this.source ? ['[' + this.source + ']'].concat(objects) : objects;
      func.apply(func, log);
      Logger.outputs.forEach((output) => output.apply(output, [this.source, level].concat(objects)));
    }
  }

with

  private log(func: Function, level: LogLevel, objects: any[]) {
    if (level <= Logger.level) {
      const log = this.source ? ['[' + this.source + ']'].concat(objects) : objects;
      func.apply(console, log);
      Logger.outputs.forEach((output) => output.apply(output, [this.source, level].concat(objects)));
    }
  }

Tell me if it solves your issue.

Seems like some versions of Firefox have this issue,

@sinedied sorry about the time gap! I tried replace like you said before and everything works OK!

I don't know if is a browser issue because I tested on Firefox and Chrome (last version) and occours the same result. I'm using node 6.9.1 and Ubuntu. When I test without change anything on my mac i haven't problems.

Can it be a problem with some dependence?

Thanks for the feedback! It's strange that it works differently depending of the platform, it may be related to the underlying implementation of the native console object.
Anyway, I'll integrate the patch in a PR since it seems some browsers on Windows also have the issue.
