This App cannot be launched while no chrome window is running.

[sunx...@gmail.com]

Hello,

I'm under Windows 10 and I'm using chrome app launcher to launch this app. in 'Open as window' mode.

I noticed that when I launch this app while no chrome window is running, the app will show blank and I can do nothing. I have to launch it again and since the last blank window is a chrome window running, the app can be launched this time.

Is this a bug or it just happens to me?

Please help me fix it.

Thanks.

open up the console (ctrl+shift+j) and see if there are any interesting errors there

Yes, It look like this:

extensions::uncaught_exception_handler:8 Error in response to runtime.getBackgroundPage: TypeError: Cannot read property 'onUpdateAvailable' of undefined

i think that's just a long standing bug.  if the background page didn't launch/initialize fast enough, the foreground window crashes trying to access the uninitialized app state.  you should be able to just close the main window and re-launch the app and it should work.

not sure what the best answer is here.  seems like the code uses the bg app just for onUpdateAvailable notifications.  if we skipped those entirely if we launched too fast, it doesn't seem like the end of the world.

So it seems that I do not have a walk-around method but to try launching again?

Thanks for your explaination:D
