Getting 500 error while calling graph client's create_group function

Objective: I want to add a MS Entra group to a ADO Group. I can successfully do it using the API POST https://vssps.dev.azure.com/<>/_apis/graph/groups?groupDescriptors=vssgp.Uy0....&api-version=6.0-preview.1

but whenever I am trying to use the following code I am getting a 500 error:

class GraphGroupOriginIdCreationContext(GraphGroupCreationContext):
_attribute_map = {
'origin_id': {'key': 'originId', 'type': 'str'}
}
graph_client = connection.clients_v6_0.get_graph_client()
def init(self, origin_id=None):
super(GraphGroupOriginIdCreationContext, self).init()
self.origin_id = origin_id

new_group = GraphGroupOriginIdCreationContext(origin_id="<>")

graph_client.create_group(new_group, group_descriptors="vssgp.Uy0....")

Can anyone tell me where I am getting it wrong or is this a bug?

从 graph_client.create_group 调用入手，将其参数与 issue 中所示的可正常工作的 Azure DevOps POST 端点进行比较。检查 GraphGroupOriginIdCreationContext 如何传递给客户端，并确定 500 错误是由客户端的使用方式还是库引起的；完成标准是记录原因并确认适当的修正方案。
