Cocoa Dialogue Issues

Will cocoa dialogue run as the root user? I'm currently getting the following error when running as a policy:

Script result: 2017-09-06 14:11:11.575 cocoaDialog[86217:1180463] CFPasteboardRef CFPasteboardCreate(CFAllocatorRef, CFStringRef) : failed to create global data<br/>2017-09-06 14:11:11.576 cocoaDialog[86217:1180463] CFPasteboardRef CFPasteboardCreate(CFAllocatorRef, CFStringRef) : failed to create global data<br/>2017-09-06 14:11:11.576 cocoaDialog[86217:1180463] CFPasteboardRef CFPasteboardCreate(CFAllocatorRef, CFStringRef) : failed to create global data<br/>2017-09-06 14:11:11.578 cocoaDialog[86217:1180463] CFPasteboardRef CFPasteboardCreate(CFAllocatorRef, CFStringRef) : failed to create global data<br/>2017-09-06 14:11:11.926 cocoaDialog[86217:1180463] CFPasteboardRef CFPasteboardCreate(CFAllocatorRef, CFStringRef) : failed to create global data<br/>2017-09-06 14:11:11.926 cocoaDialog[86217:1180463] CFPasteboardRef CFPasteboardCreate(CFAllocatorRef, CFStringRef) : failed to create global data<br/>

However everything works ok if I run it on my machine.

#!/bin/bash

lastBootTime=$(sysctl kern.boottime | awk -F'[ |,]' '{print $5}')   ## Raw unix time in seconds of last boot up
currentTime=$(date +"%s")                                           ## Current time in unix seconds
upTimeRaw=$((currentTime-lastBootTime))                             ## Calculation of difference between boot and current time ( total time up in seconds )
upTimeMin=$((upTimeRaw/60))                                         ## Calculation of uptime in minutes total ( uptime in seconds div by 60 )
upTimeHours=$((upTimeMin/60))                                       ## Calculation of uptime in hours total ( uptime in minutes div by 60 )
upTimeDays=$((upTimeHours/24))                                      ## Calculation of uptime in whole days total ( uptime in hours  div by 24 )
minusMinutes=$((((upTimeDays*24))*60))                              ## Total minutes up in whole days ( [uptime in whole days x 24] x 60 minutes )
remainingMin=$((upTimeMin-minusMinutes))                            ## Calculation of remaining minutes to subtract
remainingHrs=$((remainingMin/60))                                   ## Calculation of remaining hours to subtract
minusHours=$((upTimeHours-remainingHrs))

## Figure out minutes value for uptime display
total1=$((upTimeDays*24*60))
total2=$((remainingHrs*60))
minusMinutes2=$((total1+total2))
remainingMinFin=$((upTimeMin-minusMinutes2))

UptimeThreshold1alt=$((UptimeThreshold1-1))
UptimeThreshold2alt=$((UptimeThreshold2-1))

### Simple example, one bubble

if [ -e $CD ]
    then

$CD bubble --debug --title "Uptime Warning" --text "You haven't restarted in $upTimeDays $daysText, $remainingHrs $hrsText, $remainingMinFin $minsText Please Restart Soon!" --x-placement center --timeout 30 --background-top "FF0505" --background-bottom "FF0505" --icon "hazard"
