Magento 2.2 REST API Add Item to cart issue

Question

i have an issue with Magento ver. 2.2.0-dev i'm trying to create a cart and insert a product for a logged user, with the magento 2 rest api, but when i try to insert a product into the cart (already correctly created) it seems doesn't work and respond with this error:

 "message": "No such entity with %fieldName = %fieldValue",
 "parameters": {
 "fieldName": "cartId",
 "fieldValue": null
 },

Steps to reproduce:

• Create a cart with get rest/V1/carts/mine

• Call the rest api for
  insert product in the cart with the correct token of the user at rest/V1/carts/mine/items

• Headers: Authorization Bearer + [TOKEN]

• Body: cartItem: testing (sku of the product); qty: 1

Expected Result

• a 200 status and the json of the cart

Actual Result

{
 "message": "No such entity with %fieldName = %fieldValue",
 "parameters": {
 "fieldName": "cartId",
 "fieldValue": null
 },

How can i solve?? it's a bug or i forgot something? i've seen a lot of thread but no one can help me.

Thanks in advance!

SOLVED!

In postman, we was selecting 'form-data', but you have to select 'raw' and insert a json object like this:

{
 "cart_item": {
 "quote_id": 5,
 "sku": "testing2",
 "qty": 1
 }
}

that should work! hope it helps.
