The generator is unable to generate snmp configuration for Cisco network devices

What device/snmpwalk OID are you using?

I used the same version of snmp generatorg to generate the snmp configuration, which works well on Huawei network devices, but I encountered a problem when trying to generate it on Cisco devices

What did you do that produced an error?

The following two errors are only part of it, and in fact, all items in the walk section indicate this error

What did you expect to see?

Successfully generated snmp.yml file

What did you see instead?

I obtained OID on the following website, but it seems to be working improperly

https://snmp.cloudapps.cisco.com/Support/SNMP/do/BrowseOID.do?objectInput=IfDescr&translate=Translate&submitValue=SUBMIT&submitClicked=true

At the same time, it seems that the keyword also exists in the mib file I downloaded in the current directory

grep sysUpTime mibs/*

mibs/OLD-CISCO-CHASSIS-MIB:sysUpTimeAtLastChassisChange OBJECT-TYPE
mibs/SNMPv2-MIB.my:   sysUpTime OBJECT-TYPE
mibs/SNMPv2-MIB.my:               "The value of sysUpTime at the time of the most recent
mibs/SNMPv2-MIB.my:               "The value of sysUpTime at the time this conceptual
mibs/SNMPv2-MIB.my:       OBJECTS { sysDescr, sysObjectID, sysUpTime,

grep sysName mibs/*

mibs/CISCO-PAGP-MIB:        sysName value of the device sending the packet.
mibs/CISCOSB-CDP-MIB:            "The sysName MIB as will be advertised in subsequent CDP messages."
mibs/CISCOSB-UDLD-MIB:        "The Neighbor NeighborDevice Name TLV should contain sysName in ACSII."

mibs/SNMPv2-MIB.my:   sysName OBJECT-TYPE
mibs/SNMPv2-MIB.my:                 sysContact, sysName, sysLocation,

This is my generator.yml configuration file
