Describe the bug
I am using LargeFileUploadTask to upload files to a sharepoint directory using the following code.
The file is uploaded in visible in the sharepoint, but the code returns an error.
Code:
from azure.identity.aio import ClientSecretCredential # async credentials only
from kiota_authentication_azure.azure_identity_authentication_provider import AzureIdentityAuthenticationProvider
import os
from msgraph import GraphServiceClient
from msgraph_core.tasks.large_file_upload import LargeFileUploadTask, LargeFileUploadSession
import asyncio
from msgraph.generated.drives.item.items.item.create_upload_session.create_upload_session_post_request_body import CreateUploadSessionPostRequestBody

# Replace these with your app and tenant information
client_id = ''
client_secret = ''

file_name = ''
scopes = ['https://graph.microsoft.com/.default']
credential = ClientSecretCredential(
tenant_id,
client_id,
client_secret)
# Initialize the Graph client
graph_client = GraphServiceClient(credential, scopes)
async def upload_large_file_to_sharepoint(graph_client, site_id, drive_id, folder_path, file_path, file_name):
try:
# Create the upload session URL path
file = open(f"{folder_path}/{file_name}",'rb')
uploadable_properties = DriveItemUploadableProperties(
additional_data={'@microsoft.graph.conflictBehavior': 'replace'}
)
upload_session_request_body = CreateUploadSessionPostRequestBody(
item=uploadable_properties)
try:
upload_session = await graph_client.drives.by_drive_id(drive_id).items.by_drive_item_id('root:/export/out_seasons2.csv:').create_upload_session.post(upload_session_request_body)

# Upload the file
# The callback

print(f"Upload complete {upload_result}")
except APIError as ex:
print(f"Error uploading: {ex.message} - {ex.response_status_code}")
except APIError as e:
print(f"Error: {e}")
# Run the async upload function
asyncio.run(upload_large_file_to_sharepoint(graph_client, site_id, drive_id, folder_path, folder_path, file_name))

Expected behavior
Dont generate an error, because the file is uploaded successfully.
How to reproduce
Use my code snippet and upload a file larger than 5 mb.

Hướng dẫn đóng góp
Bắt đầu từ đâu
- Đọc hết issue, rồi đọc hướng dẫn đóng góp của dự án.
- Bình luận trên issue rằng bạn sẽ nhận — tránh hai người làm cùng một việc.
- Fork repository và làm thay đổi trên một nhánh.
- Mở pull request có tham chiếu số hiệu của issue.
Hướng nghiên cứu
Bắt đầu với msgraph_core/tasks/large_file_upload.py, đặc biệt là last_chunk, và lần theo phần phân tích phản hồi của request adapter được hiển thị trong traceback. Tái hiện vấn đề bằng đoạn mã được cung cấp và một tệp lớn hơn 5 MB; hoàn tất khi quá trình upload hoàn thành mà không gặp lỗi phân tích NoneType và trả về kết quả của nó.
Do mô hình lập chỉ mục viết ra từ nội dung của issue.
