I'm seeing a lot of intermittent 500 errors in SharePoint Online CSOM code today. This code has been in place for a long time. The errors are happening at various parts of the code, doing different things, but usually, involve downloading or uploading a file.
I can't replicate anything in the UI, so I'm hesitant to open an O365 ticket.
Two questions -
1) Do you think this a throttling issue?
2) Have you had any luck opening help tickets when the issue can't be replicated through the SharePoint UI? Mine seems to be intermittent on top of that, which would make it even harder to document.
