500 server errors from OneDrive preventing backups uploading

[truekaerf]

What would you like implemented?

I use BackupScheduler plugin to create weekly backups. Those don't appear to be noticed by your plugin. Would it be possible to add support for that?

That should work fine, both this plugin & the Google Drive equivalent were designed to work with any backup created.

Is there any indication in the octoprint.log of it not working? Can you upload it so I can look?

Ah, I see. I tracked down the log entries and there was indeed an error. So it for sure tried to upload it. Here's the relevant portions. I [REMOVED TOKENS] from the API calls for readability and security. Total file size is about 1.6 gigs. I was able to manually download from OctoPrint and then upload to OneDrive. It did successfully upload a smaller manual backup a few days earlier and I checked today and I'm still able to browse my OneDrive folders with the plugin.

Well that's fun, an internal server error from OneDrive. That would seem like Microsoft's problem to me - it's not deliberately rejecting the request because the plugin has done something wrong. Maybe it's to do with the size, I have no idea, maybe a temporary fault. The log file displays as much information as it got back from OneDrive, 'General Exception' is not helpful.

The upload URL is generated by the service and I believe it does expire if not used quite soon, but better to be safe I agree.

@truekaerf - is this a persistent issue? Or was it a temporary problem, possibly with the Microsoft servers? There's no helpful error message back from the server like there is when I do something wrong, so I don't know what I can do about it.

It seems to have been a one time issue. Last two weeks it uploaded successfully.

That's good news 😄
