This is not a question of Bar size, it is a question of whether or not there was at least one transaction during the period you query.
The bigger is the Bar, the more chance something did happen during Bar Time, also the longer the period? the more chance too.
But when I say "chance", it means that 'no data' is a valid answer, regardless of the Barsize, and you should be able to handle it, as saying there was no transaction to report.
As Richard show it, even using 1Second Bar if you query from 2023-02-17 15:59:15 to 2023-02-17 15:59:29 in 1Sec bar you will get 'no data' as there was no transaction.
Believe IB: if they say 'no data' it means no data to report as per your query.
