Hello Everybody,
Can anybody help me on **Update existing order’s Product quantity** through shopware 6 API.
I tried with end point **/api/v{version}/\_action/order/{orderId}/lineItem. ** It’s returning the 204 status. But once save the order its returning following error
**{
„errors“: [
{
„status“: „400“,
„code“: „CHECKOUT\_\_CART\_EMPTY“,
„title“: „Bad Request“,
„detail“: „Cart is empty“,
„meta“: {
„parameters“: [
]
}
}
]
}**
