An 'incorrect_offset' error from /2/files/upload_session/append_v2 indicates that the call failed because the app supplied an incorrect "cursor.offset" value in the parameters. The app and the server need to agree about where in the upload process they are in order to upload exactly the right data.

 

I recommend adding some logging to determine where/when the code is using the incorrect offset.

 

The 'incorrect_offset' error should also include a 'correct_offset' value in the response body to indicate how far along the upload session on the server is. You can parse that out and use that to automatically restart at the correct part of the file.

 

By the way, I redacted it from your post, but you originally included your access token in your code. You should revoke that for your security.
