Unable to accesss userinfo['calendarpermissions'] from forumdisplay.php

[Farcaster]

I am attempting to add the upcoming events section to the forumdisplay page. What I have found is that the calendar permissions don't seem to be loaded into the userinfo array. When I look at the value of the blow expression, it is null. Can anyone help me figure out how to get the calendar permissions loaded into the array from there?

PHP Code:

$vbulletin->userinfo['calendarpermissions']["$eventinfo[calendarid]"]
