Hi all,
This is an odd one. I'm running some Python using V4 of the Sheets API which successfully clones the first sheet in a spreadsheet to the same spreadsheet, but keeps throwing 503s when trying to copy the next sheet (index: 1.)
I've checked the sheet that's causing problems and there are no special data validation rules or null values etc. that might be causing this. I'm nowhere near the API quota limits either. Has anyone seen anything like this?
