PAN-OS Network Operations - Upgrade Assurance - First Snapshot Failure

[zallez123]

Describe the bug

Experiencing a failure with XSOAR playbook associated with Panorama Batch Firewall Upgrades within a sub playbook "PAN-OS Network Operations - Upgrade Assurance - First Snapshot".

This sub playbook stems from a main playbook "PAN-OS Network Operations - Device Upgrade". This is documented as a supported playbook, and it is recommended from Palo.

We have filled in the correct firewall device name and serial number within our panorama, and we have confirmed integrations on the panorama side as well as firewall readiness.

We verified on our end that our DNS records were consistent. The input still returns the same error code (Temporary failure in name resolution):

Expected behavior

Retrieve firewall devices to determine upgrade readiness.

Current behavior

Results in a temporary failure in name resolution. Associated log information below. AN_OS_Upgrade_Assurance returned an error
#125: Run Readiness Tests
Command:
!pan-os-assurance-run-readiness-checks firewall_serial="113101014803" check_session_exists="wuxppan10/tfw20/443"

Reason
URLError: reason: [Errno -3] Temporary failure in name resolution

Ran into programming error during implemenetation stages:

Hi @zallez123,
TypeError: can only concatenate str (not "list") to str issue should be fixed now in the main branch with the #29 - but a release is not available yet.
Regarding the URLError: reason: [Errno -3] Temporary failure in name resolution issue, check_session_exists works on IPv4 addresses for checking existing sessions on the firewall in the output of show sessions all command.
Could you please try with the following format from the latest code ?
check_session_exists="10.10.10.10/192.168.10.10/443"
