SUMMARY

network-engine 2.7.5, the error message received when the command_parser template is "missing or invalid" no longer provides the file path/name within the message, rather only "None" is provided. As seen below, the filename and path are provided when going back to network-engine 2.7.3

STEPS TO REPRODUCE

Use command_parser with any filename that doesn't actually exist (or not in the path):

    - name: PARSE THE RAW OUTPUT
      command_parser:
        file: "{{ parser_template_dir }}/ios/show_run_interface_switch1.yaml"
        content: "{{ ansible_net_config }}"

EXPECTED RESULTS

Output similar to ansible-network.network-engine v2.7.3

fatal: [switch_hostname]: FAILED! => {}

MSG:

src [/var/lib/awx/projects/net_compliance/parser_templates/ios/show_run_interface_switch1.yaml] is either missing or invalid

ACTUAL RESULTS

Paste verbatim command output between quotes below -->

ansible-network.network-engine v2.7.5

fatal: [switch_hostname]: FAILED! => {}

MSG:

src [None] is either missing or invalid
