Issue/Help with "Update a tunnel interface"

Documentation link

https://pan.dev/scm/api/config/ngfw/network/create-tunnel-interfaces/

Describe the problem

The parameter default-value isn't processed by the API.

Expected Behavior

The Tunnel interface should be created with the default-value sent to the API.

Current Behavior

The interface is created on Strata Cloud Manage but with an EMPTY "Default Interface Assignment".

Output of the API response : {'folder': 'FW-Corporate', 'id': 'REDACTED', 'interface_management_profile': 'Ping-Only', 'name': '$Tunnel-VPN-01'}

It seams like the default-value parameter doesn't work when sending an integer value. (it does nothing, no error and no return from the API.)

If i use the default_value (with an underscore and not a hyphen) with the string "tunnel.54" it works.

default-value --> default_value
int(54) --> "tunnel.54"

Reproduce (python)

PYTHON CODE :
access_token = [REDACTED]
api_url = "https://api.strata.paloaltonetworks.com/config/network/v1/tunnel-interfaces"
params = json.dumps({
"folder": "FW-Corporate",
"default-value": int(54),
"name": "$Tunnel-VPN-01",
"interface_management_profile": "Ping-Only",
})
headers = {
"Authorization": f"Bearer {access_token}",
"Content-Type": "application/json"
}
response = requests.request("POST", api_url, headers=headers, data=params)
print(response.json())

Start with the linked tunnel-interface documentation page and reproduce the POST request using the supplied Python example. Compare the hyphenated integer parameter with the working underscored string form, then determine whether the API behavior or the documentation needs correction. Done means the documented parameter behavior is accurate and the expected default interface assignment is confirmed.
