Task example:

    - name: run "show route ipv6" on remote devices 
      iosxr_command:
        commands: show route ipv6
      register: result_show_route_ipv6
    - debug:
        msg: "{{ result_show_route_ipv6 }}"
    - name: get parsed data using pyats_parser for "show route ipv6"
      set_fact:
        check_sh_route_ipv6: "{{ result_show_route_ipv6.stdout[0] | pyats_parser('show route ipv6', 'iosxr') }}"
    - debug:    
        msg: "{{ check_sh_route_ipv6 }}"

Error: FAILED! => {"msg": "Unable to parse output for command 'show route ipv6' (local variable 'source_protocol' referenced before assignment)"}

What could be the problem? Two months ago, more or less, I was able to parse "show route ipv6" using the clay584.parse_genie like this:

 tasks:
     - name: run "show route ipv6" on remote devices 
       iosxr_command:
         commands: 
            - show route ipv6
       register: result_show_route_ipv6

     - name: get parsed data using pyats_parser for "show route ipv6"
       set_fact:
         check_sh_route_ipv6: "{{ result_show_route_ipv6.stdout[0] | parse_genie(command='show route ipv6', os='iosxr') }}"

     - debug:
             msg: "{{ check_sh_route_ipv6 }}"

but now I have a similar error:

FAILED! => {"msg": "parse_genie: local variable 'source_protocol' referenced before assignment - Failed to parse command output."}

Hello @gdluca , Thanks for reporting the issue. If you can send the device output for this failures to pyats-support-ext@cisco.com so we can verify our fix.

Thanks, --Thai.

[gdluca]

Device output sent. Thanks for the support.

"show route ipv4" is working fine, sorry.

@gdluca thanks for the update.

Hello @gdluca ,

We fixed the issue and genie package v20.1 has been released with the fix. Could you please run the following command and try again to see if it works?

pip install genie.libs.parser --upgrade --pre

Thanks, --Thai.

[gdluca]

Yes, it works now!

Thanks!
