[MC-269016] The example of ATTRIBUTE_MODIFIERS on the website does not work

My command:

/give @s minecraft:iron_sword[attribute_modifiers={modifiers:[type:'minecraft:generic.scale',uuid:[1,2,3,4],name:'Big!',amount:1.0,operation:'add_multiplied_base']}]

It's said on the website:

e.g. attribute_modifiers={modifiers:[type:'minecraft:generic.scale',uuid:[1,2,3,4],name:'Big!',amount:1.0,operation:'add_multiplied_base']}

The result:

[19:28:40] [Render thread/INFO]: [System] [CHAT] Should be "]"
[19:29:27] [Render thread/INFO]: [System] [CHAT] ...iers:[type:'minecraft:generic.scale',uuid:[1,2,3,4],name:'Big!',amount:1.0,operation:'add_multiplied_base']}]<--[HERE]
