Please provide the following (and please check them off the list with [x]) before submitting this issue:

• [x] Expected behavior. Please provide links to the specific Microsoft Graph documentation you used to determine the expected behavior.
• [x] Actual behavior. Provide error codes, stack information, and a Fiddler capture of the request and response (please remove personally identifiable information before posting).
• [x] Steps to reproduce the behavior. Include your code, IDE versions, client library versions, and any other information that might be helpful to understand your scenario.

Expected behavior

Use LargeFileUploadTask to upload a file to TodoTask Attachment.

public static AttachmentSession UploadAttachment(string tasklistid, string taskid, AttachmentInfo attachmentInfo, Stream ms)
{
    var attachmentsRequestBuilder = client.Me.Todo.Lists[$"{tasklistid}"].Tasks[$"{taskid}"].Attachments;
    var uploadSession = attachmentsRequestBuilder.CreateUploadSession(attachmentInfo).Request().PostAsync().Result;
    var task = new LargeFileUploadTask<AttachmentSession>(uploadSession, ms, 12 * 320 * 1024, client);
    var res = task.UploadAsync().Result;
    return res.ItemResponse;
}

As this document illustrates, first we need to create an upload session. Here's an example of returned uploadUrl

https://graph.microsoft.com/beta/users/6f9a2a92-8527-4d64-837e-b5312852f36d/todo/lists/AAMDiFkfh=/tasks/AAMkADliMm=/attachmentSessions/AAMkADliMm=

Then we should use the upload session to upload (to /content)

PUT https://graph.microsoft.com/beta/users/6f9a2a92-8527-4d64-837e-b5312852f36d/todo/lists/AAMDiFkfh=/tasks/AAMkADliMm=/attachmentSessions/AAMkADliMm=/content

But the LargeFileUploadTask creates a request with WRONG URL

PUT https://graph.microsoft.com/beta/users/6f9a2a92-8527-4d64-837e-b5312852f36d/todo/lists/AAMDiFkfh=/tasks/AAMkADliMm=/attachmentSessions/AAMkADliMm=

Actual behavior

The data is expected to be uploaded to /attachmentSessions/AAMkADliMm=/content but not /attachmentSessions/AAMkADliMm=

Steps to reproduce the behavior

As said above, use LargeFileUploadTask to upload a file to TodoTask Attachment.

https://docs.microsoft.com/en-us/graph/api/driveitem-createuploadsession?view=graph-rest-beta

The LargeFileUploadTask is designed for uploading DriveItems which does not need /content

Considering that the Attachments API has just arrived from beta to v1.0, no one may have thought to test the usability of LargeFileUploadTask...........😥

Thanks for raising this @1357310795,

Ideally the response from the API should have the correct URL returned for uploadUrl without need for further modification. This is the case for the other APIs like the ones below.

• Outlook
• OneDriveItem
• Print API

As this API looks to still be in beta, this may be an API bug/issue. We will raise this with the relevant API team and feedback if this is indeed the intended behaviour.
