Patch application to add new app_role throws ODataError `Request contains a property with duplicate values.`

Hello,

I would like to add a new app_role called test to an app registration, I used following code, but got ODataError Request contains a property with duplicate values.:

from msgraph.generated.models.application import Application
from msgraph.generated.models.app_role import AppRole
from uuid import uuid4
# some other imports and client init ignored here, as not relevant

app_id = "an existing app id"
role_name = "test"
app_role = AppRole()
app_role.allowed_member_types = ["User", "Application"]
app_role.description = role_name
app_role.display_name = role_name
app_role.is_enabled = True
app_role.id = str(uuid4())
app_role.origin = "Application"
app_role.value = role_name
app = Application()
app.app_roles = [app_role]
# get() is OK
get_result = await client.applications.by_application_id(app_id).get()
# patch is KO
patch_result = await client.applications.by_application_id(app_id).patch(body=app)

The below command throws error: 'Request contains a property with duplicate values.' (code: DuplicateValue) after the internal command:

Could you please give a help to explain what are the duplicate values, I checked the model of app_role, it should be OK:

Comece com a chamada PATCH em msgraph/generated/applications/item/application_item_request_builder.py por volta da linha 123 e inspecione o modelo AppRole em msgraph/generated/models/app_role.py. Reproduza a solicitação usando o exemplo fornecido e determine quais valores a Microsoft Graph API trata como duplicados. Considera-se concluído quando a causa e o comportamento PATCH necessário estiverem claramente estabelecidos, com um teste de regressão ou uma atualização da documentação se o repositório oferecer suporte a um deles.
