The remapped NBT tag is possibly incorrect. Nukkit's source also uses it incorrectly.
Some useful information: How to set the tags in vanilla Minecraft Bedrock Edition: https://gaming.stackexchange.com/questions/334102/how-do-you-add-nbt-tags-to-commands-in-minecraft-pocket-bedrock-edition https://minecraftbedrock.fandom.com/wiki/Thread:217291
