Setting additional_data for DriveItemUploadableProperties throw 400

Start at the create_upload_session entry point and inspect how DriveItemUploadableProperties and CreateUploadSessionPostRequestBody serialize additional_data. Reproduce the request from the issue with msgraph.generated.models.drive_item_uploadable_properties and the @microsoft.graph.conflictBehavior field. Done means createUploadSession accepts the documented field and applies the requested conflict behavior when a file already exists.

Describe the bug

When try to add any field from the docs, such as "description" or "@microsoft.graph.conflictBehavior" to DriveItemUploadableProperties from msgraph.generated.models.drive_item_uploadable_properties msgraph throw this:

E           msgraph.generated.models.o_data_errors.o_data_error.ODataError: 
E                   APIError
E                   Code: 400
E                   message: None
E                   error: MainError(additional_data={}, code='invalidRequest', details=None, inner_error=InnerError(additional_data={}, client_request_id='463c4945-0f9c-435e-9ece-30e48ff358b6', date=DateTime(2024, 11, 6, 8, 37, 41, tzinfo=Timezone('UTC')), odata_type=None, request_id='48083d5b-ecd3-4176-8447-112ab2233e72'), message='The request is malformed or incorrect.', target=None)

code i used for this:

        sp_url = f'{self.drive_path}/items/root:{remote_path}:'
        sp_session_url = sp_url + '/createUploadSession'

        base_request_builder = (
            self.client.drives.by_drive_id(self.drive_id)
            .items.by_drive_item_id("root").create_upload_session.with_url(
                sp_session_url,
            )
        )
        create_session_response = await base_request_builder.post(
            CreateUploadSessionPostRequestBody(
                item=DriveItemUploadableProperties(
                    name=file_name,
                    additional_data={
                        "@microsoft.graph.conflictBehavior": "rename",
                    },
                ),
            )
        )

I also tried to add additional_data to CreateUploadSessionPostRequestBody but it does nothing

Expected behavior

When uploading file to Sharepoint and file with the same name already exists it must add suffix (1) or _1 to the new file

How to reproduce

try to upload file with createUploadSession if file with that name already exists using code above
