Every other methods: `error, warn, info, log` work fine and print the value, but `debug` prints nothing and no error message to be found. Using chrome `Version 59.0.3071.115 (Official Build) (64-bit)` I use in app.module: ``` import { Logger, Options as LoggerOptions, Level as LoggerLevel } from "angular2-logger/core"; @NgModule({ providers: [ { provide: LoggerOptions, useValue: { level: 5 } }, Logger ] }) export class AppModule { } ``` In the service: ``` import { Logger } from "angular2-logger/core"; @Injectable() export class MyService { constructor(private logger: Logger) { this.logger.debug("Debug message...") } } ```
