OK.
At first glance, I see you're trying to walk OID "ldskHasFailedSet", but
that's not a table, that's a NOTIFICATION-TYPE object. Presumably this is
an OID which would be used in a trap message, not an OID that you can poll
using get/getbulk. Therefore, I think even if you get the generator to
work, it's not going to do anything useful.
However, the problem you have appears to be down to how you're running the
generator and the mib files you're providing (or not providing). Since the
generator uses net-snmp to parse the files, you can get a more detailed
error if you run the "snmptranslate" command.
e.g. suppose you have the mib file in a subdirectory called "mibs" within
the current directory (but no other mibs are in that directory), and you
run the following command:
$ MIBDIRS=mibs MIBS=: snmptranslate -On ThreeParMIB::ldskHasFailedSet
No log handling enabled - using stderr logging
MIB search path: mibs
Cannot find module (SNMPv2-TC): At line 74 in mibs/ThreeParMIB.mib
Cannot find module (SNMPv2-SMI): At line 79 in mibs/ThreeParMIB.mib
Module not found (SNMPv2-MIB): At line 236 in mibs/ThreeParMIB.mib
Module not found (SNMPv2-MIB): At line 251 in mibs/ThreeParMIB.mib
Did not find 'DisplayString' in module #-1 (mibs/ThreeParMIB.mib)
Did not find 'enterprises' in module #-1 (mibs/ThreeParMIB.mib)
Unlinked OID in ThreeParMIB: threepar ::= { enterprises 12925 }
Undefined identifier: enterprises near line 81 of mibs/ThreeParMIB.mib
ThreeParMIB::ldskHasFailedSet: Unknown Object Identifier
You can see all the other mib files it's referring to, and failing to find.
Next, suppose you have a checkout of the snmp_exporter git repository, and
you are in the "generator" subdirectory. Now you type "make generate" which
fetches all the dependent mibs. After doing this, you copy the
TreeParMIB.mib file into the mibs subdirectory in addition to those already
there.
Now we see:
$ MIBDIRS=mibs MIBS=: snmptranslate -On ThreeParMIB::ldskHasFailedSet
.1.3.6.1.4.1.12925.1.2.0.21
Successful. (I strongly recommend you use the mibs downloaded by "make
generate", not any mibs you happen to have lying around on your system;
those are often broken).
Now you can run the generator, replacing generator.yml with the one you
supplied:
$ MIBDIRS=mibs ~/go/bin/generator generate
ts=2023-04-14T14:02:32.239Z caller=net_snmp.go:161 level=info msg="Loading
MIBs" from=mibs

ts=2023-04-14T14:02:32.764Z caller=main.go:91 level=info msg="Config

This has successfully generated an snmp.yml:
$ cat snmp.yml
# WARNING: This file was auto-generated using snmp_exporter generator,
manual changes will be lost.
HPE_3PAR:
walk:
- 1.3.6.1.4.1.12925.1.2.0.21
metrics: []
Don't worry about the "errors=2". I can see that "make generate" also says
there are 2 errors; this must be some other issue in the set of MIBs.
Anyway: that's how you run the generator to create snmp.yml. But in order
to get useful results, you'll have to select an OID tree that's actually
walkable.
