Product Metafields don't update with GraphiQL

Thanks ntan for your quick answer

Tried it too, still does not work.

we get similar response even when adding the valyeType as you suggested

meaybe its a matter of permissions? the get request works well but we cannot update, create or delete

and this is the reply we get
