HTTPS API for /generate not working properly for wireguard interface

I am on vyos VyOS 2025.11.04-0019-rolling using the https api. I have a simple python script to generate me a wireguard interface with its keys. when I run the code I get what looks like the correct response.

import os
import json
import urllib3
urllib3.disable_warnings()
from pyvyos import VyDevice
from dotenv import load_dotenv
load_dotenv()

hostname = os.getenv('VYDEVICE_HOSTNAME')
apikey = os.getenv('VYDEVICE_APIKEY')
port = os.getenv('VYDEVICE_PORT')
protocol = os.getenv('VYDEVICE_PROTOCOL')
verify_ssl = os.getenv('VYDEVICE_VERIFY_SSL')

verify = verify_ssl.lower() == "true" if verify_ssl else True

# Initialize VyDevice and store in app context
device = VyDevice(hostname=hostname, apikey=apikey, port=port, protocol=protocol, verify=verify)

data = device.generate(path=["pki", "wireguard", "key-pair", "install", "interface", "wg0"])

print(data.result)

Response:

1 value(s) installed. Use "compare" to see the pending changes, and "commit" to apply.
Corresponding public-key to use on peer system is: '+Nsm/cgOysi6za5TeRoEPRU5iPpitKVgTbuNX8h0Bmk='

But if I check to see if it was created properly I don’t see the new interface anywhere.

Anyone have any idea what to look for to troubleshoot this? I appreciate the help.

The response is, unfortunately, misleading; moreover, the lack of error appears to be a regression: on a system from early August:
└──> curl -k -X POST -d '{"key": "baz", "op": "generate", "path": ["pki", "wireguard", "key-pair", "install", "interface", "wg0"]}' ``https://19

One will need to adopt the recommendations in the (correct) error message in the first response. Note: to generate the key-pair, one can use the simpler:
curl -k -X POST -d '{"key": "baz", "op": "generate", "path": ["pki", "wireguard", "key-pair"]}' ``https://192.168.122.24/generate

The regression itself will need to be addressed in a bug report.

Do I need to submit a bug report or?

If you are able it would be appreciated.
