Sculk sensor's 'block destroyed' trigger doesn't activate when pistons break blocks.
How to reproduce

/gamerule doTileDrops false
Plant seeds, sugarcane, or other blocks that break off from pistons
Activate a piston far enough away or occluded by wool so that the sculk sensor won't pick up its signal
