This ABM depends on the node group, which means that the node must be registered. Hence such check should always evaluate to true. If not, then it's probably an engine bug.

Do you mean the technic_machine variable?

No, I mean the line that I commented on. if nodedef then should (in this case) be equal to if true then.

local meta = minetest.get_meta(pos)
meta:set_string("infotext", S("%s Has No Network"):format(nodedef.description))
end
if nodedef and nodedef.technic_disabled_machine_name then
node.name = nodedef.technic_disabled_machine_name
minetest.swap_node(pos, node)
end
if nodedef and nodedef.technic_on_disable then
nodedef.technic_on_disable(pos, node)
end
end
end,
})
