do you known how to write nbt tag unbreakable ?, i try a lot of time and still error

{
"mob": "minecraft:drowned",
"player": true,
"item": "minecraft:trident",
"nbt": {
"Unbreakable": ["1b"]},
}

Always be specific. You say you got an error. It is useful for me to know what error you got

I follow this example zombies will drop an enchanted diamond sword to write another nbt, but i don't know how to write true a nbt tags, i put your example in my loot.json, it's not have error but a diamond sword drop from zombie not have enchant

{
"mob": "minecraft:zombie",
"player": true,
"item": "minecraft:diamond_sword",
"nbt": {
"ench": [
{
"lvl": 3,
"id": 22
}
]
}
}

i try a lot of time to write nbt tags unbreakable but still error, i can't see the tutorital write nbt tag in your wiki or i blink

{
"mob": "minecraft:drowned",
"player": true,
"item": "minecraft:trident",
"nbt": {
"Unbreakable": ["1b"]},
}

the error i got is

JSON error in 'loot.json': check log for details (com.google.gson.stream.MalformedJonException: Expected name at line 7 column 2 path $[0].nbt)

another question, u write nbt tag with example zombies will drop an enchanted diamond sword
"id" = 22 , 22 from what, if that is enchanted iron sword, the number i put in id = ? , or other item ?
