OSAScript Errors

[josh_fischer]

Hi All, hoping for some help here. Looking to frankenstein together a script to add our admin account to FV2 as an enabled user. I've got a script that is currently working under the following conditions:

Running locally in terminal
Running manually from Self Service

It is not working when running automatically via JAMF policy. That is my goal at this point.

The script is here:

!/bin/sh

Add ADMIN ACCOUNT to FV2.sh

userName=$(/usr/bin/stat -f%Su /dev/console)
prefix='SECRET HERE'
pass=$prefix

Get the logged in user's password via a prompt

echo "Prompting ${userName} for their login password."
userPass="$(/usr/bin/osascript -e 'Tell current application to display dialog "Please enter your login password:" default answer "" with title "ADMIN ACCOUNT FileVault 2 Key Escrow" with text buttons {"Ok"} default button 1 with hidden answer' -e 'text returned of result')"

echo "Adding ADMIN ACCOUNT to FileVault"

This "expect" block will populate answers for the fdesetup prompts that normally occur while hiding them from output

expect -c "
log_user 0
spawn fdesetup add -usertoadd ADMIN ACCOUNT
expect "Enter the user name:"
send "${userName}"
expect "Enter the password for user '${userName}':"
send "${userPass}"
expect "Enter the password for the added user 'ADMIN ACCOUNT':"
send "${pass}"
log_user 1
expect eof
"
expect -c "
log_user 0
spawn fdesetup changerecovery -personal
expect "Enter the user name:"
send "${userName}"
expect "Enter the password for user '${userName}':"
send "${userPass}"
log_user 1
expect eof
"

exit 0

The error that is being thrown in JAMF is here:

Script result: Prompting joshfischer for their login password.

I have a PPPC for OSA Script applied and for Terminal. Unsure where to go from here....please help!

I seem to have found an answer with the help of a colleague...changing userPass="$(/usr/bin/osascript -e 'Tell current application to display dialog "Please enter your login password:" default answer "" with title "ADMIN ACCOUNT FileVault 2 Key Escrow" with text buttons {"Ok"} default button 1 with hidden answer' -e 'text returned of result')" to userPass="$(/usr/bin/osascript -e 'Tell application "system events" to display dialog "Please enter your login password:" default answer "" with title "ADMIN ACCOUNT FileVault 2 Key Escrow" with text buttons {"Ok"} default button 1 with hidden answer' -e 'text returned of result')" seems to have worked
