“Missing ‘}’ or object member name”

Ok. So I was on creative mode and I was trying to get the command block to give a player an enchanted netherite sword, and I got an error message saying “Missing ‘}’ or object member name”. This is the syntax I used:

/give @p netherite_sword 1 1 {[ench:

]}

How to reproduce:

1. Type this command into a command block:  /give @p netherite_sword 1 1 {[ench: {id: sharpness, lvl: 1}

   ]}

1. Activate the command block. 

Expected results: The command block should give the player a netherite sword enchanted with sharpness. 

Observed results: It sends you an error messsage saying “Missing ‘}’ or object member name.”
