Upload large file to sharepoint site using Microsoft Graph via REST API - rest

Question

I'm trying to upload a file to a specific sharepoint site. In this page shows me how to upload a sample file to user's onedrive. But, in my case, I need to upload to sharepoint. I'm trying to use this endpoint:
POST /groups/{groupId}/drive/items/{itemId}/createUploadSession
But show me this error response:
{
"error": {
"code": "itemNotFound",
"message": "Item not found",
"innerError": {
"date": "2022-05-08T23:15:29",
"request-id": "ca4362ca-ff36-488c-80b1-9f82c3448cd5",
"client-request-id": "ca4362ca-ff36-488c-80b1-9f82c3448cd5"
}
}
This is cURL:
curl --request POST \
--url https://graph.microsoft.com/v1.0/groups/{groupId}/drive/items/test.txt/createUploadSession \
--header 'Authorization: Bearer xxxx' \
--header 'Content-Type: application/json' \
--data '{
"#microsoft.graph.conflictBehavior": "rename",
"description": "description",
"fileSize": 4,
"name": "test.txt"
}'

Answer 1

You are trying to call endpoint which requires itemId but you send file name instead of itemId.
POST /groups/{groupId}/drive/items/{itemId}/createUploadSession
Another way is to specify the path to the file. The item-path must contain the name of the item that's specified in the request body.
POST /groups/{groupId}/drive/root:/{item-path}:/createUploadSession
// file system path using /drive/root:/path/to/file
POST /groups/{groupId}/drive/root:/path/to/test.txt:/createUploadSession

Here is an example of uploading a large file to SharePoint using graph API SDK Read more, step-by-step solutions
public async Task<void> Upload()
{
string site = "<YOUR DOMAIN, REPLACE HERE>.sharepoint.com";
string relativePath = "/sites/<YOUR SITE, REPLACE HERE>";
var _authProvider = _SetAuthToken();
GraphServiceClient graphClient = new GraphServiceClient(_authProvider);
Site s = await graphClient
.Sites[site]
.SiteWithPath(relativePath)
.Request()
.GetAsync();
using (var fileStream =
System
.IO
.File
.OpenRead(
#"myfile.txt"
))
{
var uploadSession = await graphClient
.Sites[s.Id]
.Drive
.Root
.ItemWithPath("sometext-1.txt")
.CreateUploadSession()
.Request()
.PostAsync();
// Max slice size must be a multiple of 320 KiB
int maxSliceSize = 320 * 1024;
var fileUploadTask =
new LargeFileUploadTask<DriveItem>(uploadSession, fileStream,
maxSliceSize);
var totalLength = fileStream.Length;
// Create a callback that is invoked after each slice is uploaded
IProgress<long> progress = new Progress<long>(prog => { });
try
{ // Upload the file
var uploadResult = await fileUploadTask.UploadAsync(progress);
//Console.WriteLine(uploadResult.UploadSucceeded ?
// $"Upload complete, item ID: {uploadResult.ItemResponse.Id}" :
// "Upload failed");
}
catch (ServiceException ex)
{
//Console.WriteLine($"Error uploading: {ex.ToString()}");
}
}
}
