use_textfsm parses different result from ntc-templates

I am using use_textfsm=True parameter in send_command to get parsed output of show version command from Cisco devices. In most cases it works like a charm except for the case in the issue.

facts = conn.send_command(command_string="show version", use_textfsm=True)

printing the facts variable I get (incorrect output):

All serial numbers and MAC addresses are just placeholders.

        "config_register": "",
        "hardware": ["C9500-32QC"],  # <-- 1 device

        "version": "17.3.1",
    }
]

On the other hand, when I use ntc-templates v2.3.1 outside of netmiko, I get the correct parsed output:

from ntc_templates.parse import parse_output

Would could be the issue? I have created an issue on ntc-templates #924 and it’s solved already.

Another option is to point directly at the Template file using the following argument to send_command

textfsm_template="/path/to/textfsm/template/file",
use_textfsm=True,

This one worked. Thanks a lot ❤️
