Cannot export xlsx

[chris-gabler]

We used to generate xls reports but faced the issue of row limit. When I try "xlsx" format instead, it gives me the following error: "Attempting to write a row[0] in the range [0,1] that is already written to disk." I tried different indices and query sizes, no one works. The query I tried: _data?format=xlsx. Please take a look

I could not reproduce it. Could you provide a step to reproduce it?
