Beginne mit msgraph_core/tasks/large_file_upload.py, insbesondere mit last_chunk, und folge der in der Traceback gezeigten Parsing-Logik für die Antwort des Request-Adapters. Reproduziere das Problem mit dem bereitgestellten Code und einer Datei, die größer als 5 MB ist; fertig ist es, wenn der Upload ohne den NoneType-Parsing-Fehler abgeschlossen wird und sein Ergebnis zurückgibt.

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.models.drive_item_uploadable_properties import DriveItemUploadableProperties

from kiota_abstractions.api_error import APIError

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

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'}
        )

        except APIError as ex:
                print(f"Error creating upload session: {ex}")

        # to be used for large file uploads

             large_file_upload_session,
             graph_client.request_adapter,
             file)
        total_length = os.path.getsize(f"{folder_path}/{file_name}")

        # Upload the file
        # The callback
        def progress_callback(uploaded_byte_range: tuple[int, int]):
            print(f"Uploaded {int(uploaded_byte_range[0])/1024/1024:.2f} MegaBytes of {int(total_length)/1024/1024:.2f} MegaBytes\n")

        try:
            upload_result = await task.upload(progress_callback)
            print(f"Upload complete {upload_result}")
        except APIError as ex:

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.
