How to get the pGuid

Hi,

I'm trying to get this working, but it just returns nothing (I've got all of the parameters, and receiving no errors). Are there any known issues? Or restrictions beyond those made in the comments?

Is anyone able to support me?

Thanks

I got some errors on line 35,
in fact it seems it can't log in calendar...
does things have changed in apple server?
for exemple is adress still pxx-caldav.icloud.com/ or is it now pxx-calendarws.icloud.com

and on ical, is work calendar pGuid still "work" ?
