Download in .xlsx is empty,no data

download from application in .xlsx is empty,no data.

Is it only for this question you experience this problem? How many rows are in this question? Does export to CSV format work?

Any info in the error log when you try to export?

@samantha - is this also with an embedded dashboard for you?

GitHub issue above works in v0.30 - @samantha does it also fix your problem too?
