File Corruption in SharePoint Upload via Microsoft Graph API

Bắt đầu với nhánh simple-upload trong đoạn mã uploadFile được cung cấp và xem xét cách document.contentToStream được sử dụng bởi lệnh gọi Microsoft Graph SDK 5.80.0. Tái hiện trường hợp xảy ra không liên tục trong khi so sánh kích thước nguồn, kích thước trên SharePoint sau khi tải lên và thời điểm của webhook; được xem là hoàn tất khi đã xác định được nguyên nhân đáng tin cậy và một cách khắc phục đã được xác minh.

Describe the bug

I am using the Microsoft Graph API 5.80.0 to upload files to SharePoint from a Java Spring Boot application. The upload works fine in normal conditions, but some files become corrupted while uploading & so unable to download from SharePoint.

Most of the upload files are smaller than 4 MB, so I am using the simple upload method (PUT request).
The upload process completes successfully (returns 200 OK with a valid file ID). When I receive the webhook for the same the file size is 0 & not able to open the file as the file is corrupted. It happens randomly for a few of the requests.

private fun uploadFile(document: DocumentUploadStream) {
    val timeMillis = System.currentTimeMillis()
    val buildDriveItemRequest : DriveItemRequestBuilder = microsoftGraphClient.drives("driveId").root().itemWithPath(document.path)

    
    if (document.size < 4 * 1024 * 1024) { 
        // Simple upload for small files
        val driveItem = retry {
            refreshToken { 
                buildDriveItemRequest.content().buildRequest()
                    .put(document.contentToStream.readAllBytes()) 
            }
        }
        logger.info { "Upload done ${document.path}, id: ${driveItem?.id}, time: ${(System.currentTimeMillis() - timeMillis)/1000}s" }
        document.id = driveItem?.id
    } else { 
        // Large files use upload sessions (this part is working fine)
    }
}

data class DocumentUploadStream(
        val path: DocumentPath,
        val contentToStream: InputStream,
        val size: Long
)

Expected behavior

The file should not get corrupted on upload.
Any insights or recommendations would be greatly appreciated!
Thanks
