Attempting to modify NBT of killer rabbit throws unexpected error

When trying to use the command below, the error message "An unexpected error occurred trying to execute that command" appears in chat.

data merge entity @e[nbt={RabbitType:99},limit=1] {DeathLootTable:"air"}

However, you can summon a rabbit entity with any DeathLootTable.

summon rabbit ~ ~ ~ {DeathLootTable:"air",RabbitType:99}

 
Tested in 1.20.6 and it works perfectly, so only the latest snapshot seems affected.
