Agreement

• I have read the guidelines above and affirm I am following them with this report.

[NotSoDelayed]

Further testing shows that spawning a falling block with SkBee's NBT throws the exact same error.
Code used: spawn falling block with nbt compound of "{BlockState:{Name:""minecraft:sand""},Time:1,DropItem:0b,HurtEntities:0b}"

[TPGamesNL]

As a workaround, specify the type of falling block, e.g. falling stone.

FallingBlockData#types is nullable, but the spawn method doesn't deal with this properly.
