I was trying to add more loots on to zombies and villager golems and I keep getting errors on start. What should I change in my code?

`[

{
"mob": "minecraft:zombie",
"player": true,
"item": ["minecraft:nether_star", "minecraft:trident"],
},

{
"mob": "villager_golem",
"player": false,
"item": ["minecraft:diamond", "minecraft:gold"],
}

]`
