Hi Radovanhodor,

The mutation does look correct so one thing I would check for is that the access token you're using for the API call is correct and has the necessary access scopes. If you're using an old or incorrect token, it might not have the required permissions. Also which version of the Storefront API is your app on? 

Hope this helps,
