We are currently running our application on Azure in the 21Vianet environment in China. When using the following API
(Graph API, download a file in another format, GET /drive/items/{item-id}/content?format={format}),
we are encountering a 503 error. The official documentation(https://learn.microsoft.com/en-us/graph/api/driveitem-get-content-format?view=graph-rest-1.0&tabs=http) indicates that 21Vianet in China supports this interface. Is there any restriction that we should be aware of?
