Script no longer successfully calls Policy

My deployment method involves a policy triggered by enrollment. That policy runs a script that names my computers based on a CSV stored online, and at the end of the script, calls the next policy that begins installing software.

Recently, the call to the second policy has failed completely. The first script runs fine still, but it will never call the second policy. I have been racking my brain over this for two weeks and I cannot figure out why it no longer works.

I have not edited the scripts at all, though we did upgrade our server version recently.

Below is the script that runs upon enrollment. The only really important part is the if statement at the end, which does come back positive (confirmed by the echo in the logs) but still does not run the final command before the exit 0.

Please help!

# Rename Computer from Index File
# Written by KClose.
# Created 02/20/2019.
# Updated 02/21/2019 - Added reporting log and ARD Info flag.
# Updated 05/07/2019 - Fixed success/failure testing. additional failure check included. Success triggers next imaging script.
# Updated 05/13/2019 - Added Presorting Flag.
# Updated 10/09/2019 - Changed -trigger to -event and found a missing $.
# Updated 10/15/2019 - Extended the Recon call with the exact path to the jamf command and extended the sleep.
#
# Based on a script by Yonathan Khoe
# Updated to not need any user interaction.
# Index file must be updated prior to script running on new computer.
# Index file can be found at:
#     [file reference removed]
#
# There must be a domain user with access to the network resource.
#     The login credentials should be added in the options of any policy that uses this script.
