How to use JamfHelper to create a notification and button that will open a self service policy?

[PEBKAC]

Here is the script I am currently using. I would like to convert it to Jamfhelper so I can use a logo which using the below console output workflow does not allow.  Does anyone know how to convert this to use jamfhelper?

#!/bin/bash

user=`/bin/ls -l /dev/console | /usr/bin/awk '{ print $3 }'`
#get User ID
uid=$(id -u "$user")

#Display a message to the user and if they click OK it will open the Self Service Policy

#Message I want to Display- Make labels in Jamf
messageToDisplay="$4"
policyIDtoExecute="$5"
policyAction="$6"

#This will use a here doc MUST PUT ENTER/RETURN AFTER EOF
#EOF is an example. You can use ANY word.. IE SHUTTLECOCK
buttonClicked=$(launchctl asuser "$uid" /usr/bin/osascript << EOF
button returned of (display dialog "$messageToDisplay" buttons {"Delay Upgrade", "Upgrade"} default button 1)
EOF
)

echo "$buttonClicked"
# For paramter six we are going to view or execute
if [[ "$buttonClicked" == "Upgrade" ]];then
/bin/launchctl asuser "$uid" /usr/bin/open "jamfselfservice://content?entity=policy&id=$policyIDtoExecute&action=$policyAction"
fi

Try this:

#!/bin/bash

user=$(/bin/ls -l /dev/console | /usr/bin/awk '{ print $3 }')
#get User ID
uid=$(id -u "$user")


#Display a message to the user and if they click OK it will open the Self Service Policy

#Message I want to Display- Make labels in Jamf
messageToDisplay="$4"
policyIDtoExecute="$5"
policyAction="$6"

buttonClicked=$("/Library/Application Support/JAMF/bin/jamfHelper.app/Contents/MacOS/jamfHelper" \
	-windowType utility \
	-title "" \
	-description "$messageToDisplay" \
	-button1 "Delay Upgrade" \
	-button2 "Upgrade" \
	-defaultButton 1 \
	-icon "/path/to/icon.png")

echo "$buttonClicked"
# For paramter six we are going to view or execute
if [[ "$buttonClicked" == "2" ]];then
	/bin/launchctl asuser "$uid" /usr/bin/open "jamfselfservice://content?entity=policy&id=$policyIDtoExecute&action=$policyAction"
fi

You might need to experiment with this, because jamfHelper has a size limitation for button length. The "Delay Upgrade" button label looks like it gets cut off a little in my quick tests.

Thanks so much! This does work, but for whatever reason it fails if I try to run it as standard user (without admin privelages) the message will appear but when I click the button to launch self service I get a message that pops up saying Self Service Crashed with an error. (works flawlessly on admin machines however.) Here is the full error output:

@PEBKAC I'm not exactly sure what you mean when you say you're running it as a standard user. You mean the script itself, or the policy is running while a standard user is logged in? You can't really run the script itself as a standard user, in case that's what you were attempting. The launchctl asuser syntax requires that to be running as an admin or root preferably, so it can run the command that follows as the user account you specify.

If you're seeing those errors when a standard user is logged in and the policy runs, then there's something wrong with the script syntax. I did notice you are using this:

/bin/launchctl asuser "$uid" /usr/bin/open "jamfselfservice://content?entity=policy&id=$policyIDtoExecute&action=$policyAction"

I've often found this to be more reliable:

/bin/launchctl asuser "$uid" sudo -iu "user" /usr/bin/open "jamfselfservice://content?entity=policy&id=$policyIDtoExecute&action=$policyAction"

 Try adding that if those errors are coming up when the script runs from a regular Jamf Pro policy.

@mm2270 Have you seen any issue with Self Service crashing when being called from a script triggered via a LaunchDaemon?

I'm seeing Self Service 10.40.1 on macOS 12.5.1 crash due to a SIGABRT when launched that way. Running the same script from Terminal via sudo does successfully launch Self Service. The script _should_ be doing all the needed things to open Self Service in the user context: 

/bin/launchctl asuser "$currentUserID" sudo -u "$currentUser" /usr/bin/open "jamfselfservice://..."

I have customized this script and it does work, many thanks! But after clicking to upgrade self-service opens and then prompts for login. How do I get the policy to be front and center for an end-user to execute without logging into the app?

Thank you.

The script above worked very well. I made a few changes as I could not get the variables to stick to the correct information to be used. But actually putting in the script "policy ID" and "action" worked very well. 

I was also getting the following after the helper prompt was clicked to action. But it had more to do with the self-service... string was wrong (for me). I copied it right from the console and edited and it worked nicely.

 This is what I put together.  Thanks again!
