pysnmp-lextudio using next() with the getCmd() generator leads to TypeError: 'tuple' object is not an iterator

I have removed pysnmp and installed pysnmp-lextudio in an attempt to bring my codebase up to python 3.12.2

Code that ran with previous pysnmp versions now returns the error:'tuple' object is not an iterator

Offending code is next() of last line:

from pysnmp.hlapi import *g = getCmd(SnmpEngine(),    CommunityData('community', mpModel=1),    UdpTransportTarget((ipAddress, port)),    ContextData(),    ObjectType(ObjectIdentity('SNMPv2-MIB', 'sysDescr', 0)))errorIndication, errorStatus, errorIndex, varBinds = next(g)

Any insight is welcome, device behaving via snmp walk.
