Error 500 finishing huge file upload (300GiB+)
Hello, When a huge file (300GiB+) is uploaded using the upload_session API an "Error 500 Internal Server Error" is received when the last part is uploaded (/upload_session/append with close set). ...
Hi pp111,
Up border of acceptable file size is 350GiB. If your file doesn't cross this border, then maybe this is some glitch of new bug. It may be useful for support people to have multiple x-dropbox-request-id from your failing requests for debugging. Perform some more such requests and post here their id values.

If you don't upload files in batch, you don't need to close your sessions during last append. The session will be closed automatically during finalization if not yet. You may try use this way as a workaround.
Good luck.
Thank you.
I confirm that my file is smaller than 350GiB, actually it is exactly 311GiB. And, of course, I have enough free space.
I tried what you suggested and, instead of sending the last part with close set, I directly call upload_session/finish. In this case the last part is uploaded correctly but I get the Error 500 in the upload_session/finish call. I retry the finish call many times, but I get the Error 500 during at least 1 hour after the last part was uploaded.
These are a few x-dropbox-request-id of the failed upload_session/finish calls

pp111 Thanks for the samples! We'll look into it and follow up here once we have any updates on this for you.
Hello,
The issue is still not fixed and it is still not possible or reliable. We keep retrying the upload_session/finish call during hours, but the upload does not finish and we keep getting the error 500.
Do you have new information or a workaround we could use?
Thanks

This is open with engineering, but I don't have an update on it yet. I'll check in with them and follow up here once I have any news.
