While trying to parse cisco_asa show route getting this error:
textfsm.parser.TextFSMError: State Error raised. Rule Line: 12. Input Line: Codes: L - local, C - connected, S - static, R - RIP, M - mobile, B - BGP

Is this still occurring?
I cannot replicate this with the example output that is on this issue.
@mksbcisco
Would you please respond whether this issue is still happening for you?
I cannot replicate the problem.
And there haven't been many changes to that template either.

Given the template status in January 2023, I'm not sure how that error could have been occurring. The ^. -> Error
lines required by this ntc-templates project weren't added until March 2024 via PR #1636.
The rest of the earlier git history does not show any signs of there being a problem. Nor could I replicate it in August 2023.
unable to reproduce issue, and lack of response
