...errBut this did no conflicts in 1.13.x?

The sound freaked me out
And the arrow with potion particles around,seems to be tipped
I tried another command:

summon minecraft:arrow ~ ~1 ~ {Motion:[0.0,0.0,1.0]}

summon minecraft:arrow ~ ~1 ~ {Motion:[0.0,0.0,1.0]}

And arrow summoned by command block with this command also plays that cave sound when hit any blocks in the same chunk with potions' particles floating nearby
