Add/Update custom tags (columns) of a DriveItem

[ZyxwvuTJ]

So far using O365 I've been able to successfully upload a pdf file using the One Drive upload_file() to a SharePoint site. I'm also able to navigate to a SharePoint item that was previously uploaded via SharePoint ui and update_fields(). But, when I try to update fields to a pdf that I recently uploaded, I get an error that those fields don't exist.
Is it possible to upload a file and then immediately update custom column fields? The documentation states that a DriveItem.update() currently only support updates to name and description. Are there any work arounds or better ways to solve what I'm trying to accomplish?

I did end up finding a workaround and wanted to provide it here in case someone else finds this. O365 does provide the ability to do generic requests without having to worry about authentication which was nice. I did this to update the custom fields:
r = account.connection.oauth_request(r_url, 'patch', headers=r_type, data=r_fields)
This is the resource that helped me figure it out:
