Making invincible custom armor,dunno what 's wrong

so i make a armor that can withstand any condition but when i try to spawn it ,it always says"could not load item'floran tier6schest' "

/spawnitem florantier6schest '{"statusEffects":[{"stat":"protection","amount":500},{"stat":"maxHealth","amount":800},{"stat":"powerMultiplier","baseMultiplier","amount":10},{"stat":"maxEnergy","amount":750},"glow","rage","healingwater","nofalldamage","runboost","jumpboost","swimboost","thorn","energyregen","fireblock","electricblock","iceblock","poisonblock"],"level":10}'

anyone can help found the mistake/problem contained within the code

 

some of those might need amounts? Im not sure, like rage has a duration, so you may need something like {"rage", 500} so it has a duration. I do not know off hand how many of those stats require a duration

 

i don't know about the duration but the effect keep going like it was infinity also i noticed the problem "/spawnitem florantier6schest" it should be "/spawnitem florantier6schest 1"

 

i finally completed the code but the chest piece cannot spawn and is there any stat limit for armor ?

/spawnitem florantier6shead 1
'{"shortdescription":"Assassin Head Gear",
"description":"We walk in the dark",
"rarity":"Essential",
"statusEffects":
["rage","jumpboost","healingwater","energyregen","iceblock",{"stat":"powerMultiplier","baseMultiplier":6},
{"stat":"protection","amount":200},
{"stat":"maxHealth","amount":500},
{"stat":"maxEnergy","amount":500}],"level":10}'

/spawnitem florantier6schest 1
'{"shortdescription":"Assassin Chest Gear",
"description":"To serve the light",
"rarity":"Essential",
"statusEffects":
["rage","healingwater","nofalldamage","fireblock","electricblock",
{"stat":"powerMultiplier","baseMultiplier":8},
{"stat":"protection","amount":250},
{"stat":"maxHealth","amount":550},
{"stat":"maxEnergy","amount":550}],"level":10}'

/spawnitem florantier6spants 1
'{"shortdescription":"Assassin Leg Gear",
"description":"We are Assassins",
"rarity":"Essential",
"statusEffects":
["glow","rage","runboost","healingwater",
"poisonblock",{"stat":"powerMultiplier","baseMultiplier":8.5},
{"stat":"protection","amount":200},
{"stat":"maxHealth","amount":500},
{"stat":"maxEnergy","amount":500}],"level":10}'

 

the problem in the chest located in statowermultiplier because i put amount after i remove it it still can't load the item
