Panic with SYNOLOGY-DISK-MIB::diskTable about gosmi HOT 3 CLOSED

This is the output I get when I run the attached go program with the standard IETF MIBs and the provided Synology MIBs loaded:

$ go run synology.go
.1.3.6.1.4.1.6574.2.1
node: diskTable
get index: [{{ReadOnly ObjectType The index of disk table Column diskIndex 1.3.6.1.4.1.6574.2.1.1.1 11 Current Type[Integer32 Status=Unknown, Format=, Units=]} 0xc001d09b80 Type[Integer32 Status=Unknown, Format=, Units=]}]
index: map[diskIndex:{}]
order: [diskIndex diskID diskModel diskType diskStatus diskTemperature diskRole diskRetry diskBadSector diskIdentifyFail diskRemainLife diskName]

One potential flaw that I see in the provided code is that you have a qualified name in your lookup, but you are completely ignoring the module, which might be causing an issue. You are also not returning after an errored GetNode call. I would suggest doing something like this instead:

...
s := strings.Split(oid, "::")
moduleName := s[0]
module, err := gosmi.GetModule(moduleName)
if err != nil {
  fmt.Printf("%v", err)
  return
}
node := s[1]
out, err := module.GetNode(node)
if err != nil {
  fmt.Printf("%v", err)
  return
}
...

As you already have the node in out at this point, I'm not sure why you are then looking it up again by OID with gosmi.GetNodeByOID(types.OidMustFromString(oidNum)). Also, if you know the module name, then it's unnecessary to load all the files in the paths first.

Thank you for your help. I will implement your suggestion :)
