[pptyasar]

Cannot read property 'subscribe' of undefined

.... constructor( private userIdle: UserIdleService) {...

....this.userIdle.ping$.subscribe(() => console.log("PING"));....

Same issue, can not subscribe to ping.

@pptyasar and @sameer-coditas , you should both update this issue with things like

a) version of the library
b) version of angular you are using
c) maybe even a minimal reproduction project

Otherwise, I'd expect troubleshooting this will be hard for the maintainers and community at large.

@pptyasar @sameer-coditas is this issue still happening || valid?

I think the issue is ping$ only gets initialized after startWatching() has been called. So, if someone subscribes to ping$ before startWatching() is called there will be no Observable to subscribe to.

I also had issues with the ping. Sometimes the ping wouldn't start. And when it started, I could never get it to stop, despite resetting the timer, stopping the timer, or stopping watching. I ended up just writing my own ping timer that worked with this package and now it's doing everything I need.

Can you share a sample? I'm living the same problem
