Expected positive integer for bottom but received -96409 of type number

What Happened#

2026-05-26 13:24:47 UTC에 cupixworks-any-floorplan-agent 서비스에서 floorplan 87012를 타일링하는 과정에서 sharp 라이브러리의 extend() 호출 시 bottom 파라미터에 음수 값(-96409)이 전달되어 에러가 발생했다. 이미지의 실제 높이가 maximumPixels (65,536)보다 커서 extend 계산 결과가 음수가 된 것이 원인이다.
