It looks like your MIB is broken or corrupt.

Can this be reason for exporter not scraping data from device agent?

[lZzozZl]

I manage to make it work. Now i can scrape some data from device agent.
I think i had wrong line in generator.yml

But still seeing this errors while trying to generate a snmp.yml file

and when using snmpwalk still seeing those errors.

Could someone help with that ?

I think your CISCOSB-MIB is corrupt. I suggest downloading it from https://github.com/librenms/librenms/blob/master/mibs/cisco/CISCOSB-MIB.
