Full Page URL Tracking in g page varible

Hi,

I am encountering a issue where "g" page variable is capturing full URL with  page view call but not in event call. we haven't use custom code to set "g".

pageview call]  g=https://abc.demo.com/minigame/quiz/90863363-89ff-4dd4-89bc-6bcd71bf429c

event call] g= https://abc.demo.com/

Any help in this regards highly appreciated.

Thanks

Aw Kumar
