Question Execute Command with certain NBT data not working

I tried these commands in singleplayer and they both work.


/give @p iron_boots{display:{Name:"[{\"text\":\"Speedy Boi\",\"italic\":false}]",Lore:["[{\"text\":\"Speed 2\",\"italic\":false}]"]},Unbreakable:1} 1


/execute as @a[nbt={Inventory:[{Slot:100b,id:"minecraft:iron_boots",tag:{display:{Name:"[{\"text\":\"Speedy Boi\",\"italic\":false}]"}}}]}] run effect give @s jump_boost 1 1 false

However, only the first command is working on bukkit servers, even before I added any plugins. My commands.yml looks like this

command-block-overrides:
- '*'
ignore-vanilla-permissions: false
aliases:
icanhasbukkit:
- version $1-


Why doesn't the second one work?
