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:

msgraph/generated/applications/item/application_item_request_builder.py の 123 行目付近にある PATCH 呼び出しから始め、msgraph/generated/models/app_role.py の AppRole モデルを調べてください。提供されている例を使ってリクエストを再現し、Microsoft Graph API がどの値を重複として扱うかを特定してください。原因と必要な PATCH の動作が明確に確立され、リポジトリが対応している場合は回帰テストまたはドキュメントの更新が行われていれば完了です。
