Updating Stock Status Via REST API

[roman_polevecko]

Hi guys
I'm having a problem updating a stock status when updating it via API.

I've been getting this error
"The stock item was unable to be saved. Please try again."

But it works just fine with the same request from Postman

I'm following the SWAGGER documentation

What works in postman:

https://store/index.php/rest/V1/products/DIG11925/stockItems/2725
headers:
content-type: application/json

Authorization: Bearer rgme26l6eg1rkoftm0f510qi0zzexk24g

body:

{
"stockItem": {
"is_in_stock": true,
"qty": 1
}
}

When performing this request in postman I'm getting back

"2725" (which is itemid) and item gets updated just fine

if I perform the same in JS script I'm always getting a "The stock item was unable to be saved. Please try again."

I've checked the script 100 times and I can't see anything different in it....

                    var stockDataNewJSON = {};
                        stockDataNewJSON.stockItem = {};
                        stockDataNewJSON.stockItem.qty = Number(document.getElementById("quantity-held").value);
                        if (document.getElementById("inputGroupSelect01").value === 1) {
                            stockDataNewJSON.stockItem.is_in_stock = true;
                        }
                        else {
                            stockDataNewJSON.stockItem.is_in_stock = false;
                        }
                    fetch('https://store/index.php/rest/V1/products/' + productData.sku + '/stockItems/' + stockData.item_id, {
                            method: 'PUT',
                            headers: {
                                'content-type': 'application/json',
                                'Authorization': 'Bearer ' + magentoToken
                            },
                            body: JSON.stringify(stockDataNewJSON)
                        }).then((response) => {
                            return response.json();
                        }).then((data) => {
                            resolve(data);
                            console.log(data);
                            alert(JSON.stringify(data));
                        });
