Error Fetching Device Environment Data

[AskskwBv8T2nrm4Qnj]

Hi,

In the Netbox web-interface when going to the Status window of my device, I get the following error:

Error Fetching Device Environment Data
Method get_environment failed: 'NoneType' object has no attribute 'group'

The Status window has partially filled in information. Below "Device Facts", everything is filled except for: FQDN, Model and OS Version. These 3 fields have as value "unknown". Below "Environment" no information is filled.

Running Netbox locally I get the following result:

python3 manage.py runserver 0.0.0.0:8000 --insecure

Running the following, I get a stack-trace:

>>> device.get_environment()

                                         ^^^^^^^^^^^^^
AttributeError: 'NoneType' object has no attribute 'group'

File /opt/netbox-3.7.4/venv/lib/python3.11/site-packages/napalm_huawei_vrp/huawei_vrp.py contains the following code:

        fan_output = self.device.send_command(fan_cmd)
        power_cmd = self.device.send_command(power_cmd)
        temp_cmd = self.device.send_command(temp_cmd)
        cpu_cmd = self.device.send_command(cpu_cmd)
        mem_cmd = self.device.send_command(mem_cmd)

fan_cmd = "display fan"
power_cmd = "display power"
temp_cmd = "display temperature all"
cpu_cmd = "display cpu-usage"
mem_cmd = "display memory-usage"

None of the display commands listed above, exist on my Huawei Cloudengine. However, I do have the "display health" command, that displays the same information but sorted differently.

I have tried the 5 display commands on 2 Cloudengines running VRP "Version 8.180" (2018) and "Version 8.191" (2020) respectively.

In short, I think the ""def get_environment(self)" function should be modified to use the results of "display health" instead.

Thank you for your continued development.
