Thanks murrant,
I see now that I have an old pppoe custom discover for ios-xe so thanks for pointing me in the right direction.
I have this file in untracked “includes/discovery/os/iosxe.inc.php”, i realized this is due to custom discovery i setup ages ago for PPPoE Sessions for “CISCO-AAA-SESSION-MIB” for ios-xe devices ages ago Graphing PPPoE sessions on Cisco device
i’m guessing this now causes a problem with the new discovery changes maybe? i’ll delete the file and hopefully it is fixed now
