Using version 3.0.0 i implemented batch because our app was being throttled and now i am randomly getting socket errors... it works few times then errors few times etc... How can i fix my error?

Error:

Bắt đầu từ MicrosoftGraphClient.getUserCalendarFreeSlots và lệnh gọi BatchRequest.post, sau đó lần theo lỗi đã báo cáo qua CoreHttpProvider.sendRequestInternal. Tái hiện batch request xảy ra không liên tục và so sánh các trường hợp timeout với socket bị đóng; được xem là hoàn tất khi đã cô lập nguyên nhân trong đường dẫn request của SDK hoặc trong cách sử dụng client được cung cấp.
