testing the sample main.go file under cmd/smi example but facing Null oid error

[kaushiksrinivas]

When we try to test out the example go code to load a module from mib and inspect the nodes, we only null being shown as the oid for the nodes. Tried with sample mibs in this repo as well as some standard mibs. Can you point if there is any issue in the way the go code is executed ?

go run main.go -d -m FIZBIN-MIB -p .

-p -> pointing to directory where the mib file is placed
-m -> FIZBIN-MIB is the module name of the sample mib present in this repo.

why is the oid is null and length shown as 0 ?

@sleepinggenius2 , can you support please ?

[sleepinggenius2]

The referenced MIB imports SNMPv2-SMI, but I do not see that it is being loaded. Please make sure that it is directly loaded first or an appropriately named file is present in the search path to be autoloaded.

Thank you @sleepinggenius2 .
I was able to load the OIDs after keeping those imported module named files in the same path.
