Issue with systemd graph showing "No Data file"

I am facing an issue where the graphs for systemd app are showing “No Data file”.

I checked the poller and it is getting the output of the script over snmp:

Application: systemd, app_id=2SNMP[[0;36m'/usr/bin/snmpget' '-v3' '-l' 'authPriv' '-n' "" '-a' 'SHA' '-A' 'PASSWORD' '-u' 'USER' '-x' 'AES' '-X' 'PASSWORD' '-Oqv' '-m' 'NET-SNMP-EXTEND-MIB' '-M' '/opt/librenms/mibs' 'udp:HOSTNAME:161' 'nsExtendOutputFull.'[0m]

The rrd files are also being created for systemd: Untitled - LibreNMS

Not sure what the issue is here, I do see in release 24.3 there was some rework done of the systemd poller/app. Not sure if it is related.

This is a fresh install.

Poller output: Untitled - LibreNMS
