Microsoft Graph Subscription API started returning HTTP 308 with no Location
问题 We have some production code that deletes an existing subscription in certain cases. We started getting a HTTP 308 response to certain DELETE requests but we can't identify why this is occurring or what the relevance of the 308 is. There doesn't seem to be any information on a 308 in the Graph Docs; HTTP specs indicates this is a permanent redirect. There is no location header provided. Our request is pretty simple: DELETE https://graph.microsoft.com/v1.0/subscriptions/c9ec8a0f-0c9d-492c-90a8
