Describe the bug

QuestDB throws an error if my query returns 0 rows when using SAMPLE BY. It works fine and responds 0 row found without SAMPLE BY.

My query (I run it on QuestDB web console directly)

SELECT ts, pair, side, round(nsum(size)) as size
FROM liquidations
WHERE pair = 'ETC-USDT-PERP' and side = 'sell' and size > 500
SAMPLE BY 1m
ALIGN TO CALENDAR WITH OFFSET '00:00'
