Any specific page or action you invoke when this happens?

[Lee Jose]

This happens after a service has been invoked on page load.

Hello! Could you send us your app link so we can test it (make it public before)

[Lee Jose]

Here you go app link

[Maryna Brodina]

Thank you! Could you clarify please what service on what screen is caused this problem? Also what login/password do you use to test or it's possible to reproduce your problem with any login/password?

[Lee Jose]

You can just click on the login button for faster testing. You can click on the top image, labeled UCC Christmas . . . and it will take you to the page that triggers the error.

[Maryna Brodina]

On screen raffle there is a service raffleViewService. On Request mapping you have JS

var ret = parseInt(localStorage.getItem("selectedRaffleId"));
return ret;

But in localStorage variable selectedRaffleId is empty, that's why you get empty response and error.

Thanks Marina, I'm receiving no errors now.
