[IOS-XE] [Help Wanted] show rep topology detail when ring is broken and the ring has failed ports parser is empty

[ajackson79]

So if I run the parser when the rep ring is in a broken state because of a fiber cut, instead of returning what data it could I get a SchemaMissingKeyError and no data at all is returned. I know the data that would be returned will be incomplete, but is there a way to handle that error and have it return what data it can collect and ignore the missing keys?

Example output from a failed interface:

DEVICE_NAME, Te0/0/6 (Intermediate)

Port Number: 00C
Port Priority: 800
