Curl Patch does not update Inventory

I use this command which is from https://developer.sellbrite.com/v1.0/reference#inventories

curl --user : -X PATCH -H "Content-Type: application/json" -d '{ "inventory": [{"sku":"00002640","description":"NEW Snom M9 2640 Combo Kit IP Phones 2 Handsets, 2 Bases, 2 Batteries, 2 Power Supply”,”warehouse_uuid":"e1f883ca-88b2-4548-95bd-bb028ef8bbac"","on_hand":"1"}] }' https://api.sellbrite.com/v1/inventory

I tried to change description with same SKU but when I check my inventory with

curl --user : "https://api.sellbrite.com/v1/inventory"

got respond but nothing is update. the user ID for this account is [email protected]

please advice
