genie.metaparser.util.exceptions.SchemaMissingKeyError: Show Command: show spanning-tree

[xjs678qr]

Hi,

I encounter some missing key exceptions on the 'stp' model (Stp.Learn) for IOS-XE (running 17.3.4)

Missing keys: [['rapid_pvst', 'vlans', 2135, 'interfaces'], ['rapid_pvst', 'vlans', 2140, 'interfaces'], ['rapid_pvst', 'vlans', 2145, 'interfaces'], ['rapid_pvst', 'vlans', 2151, 'interfaces'], ['rapid_pvst', 'vlans', 2157, 'interfaces'], ['rapid_pvst', 'vlans', 2160, 'interfaces'], ['rapid_pvst', 'vlans', 3346, 'interfaces']]

Caught error while executing target in child process-4:

Hi, i think the pattern is matched from the device output is not matching the output schema. You can start investigating from there, or you can share the device output with us and the commands you used.

Hi,

I can reproduce with the following command:
genie learn stp --testbed Testbed.yaml --output STP

This is the beginning of the exception file (it's very long, I can send it to you in private if you prefer).

Hi, can you send me the testbed file via duchnguy@cisco.com?

Done!

Hi sorry for the late response, so far the issue relates to the parser show spanning-tree detail, as the parser library is community-driven, we recommend you to try modifying this parser to match your needs.
