Change multiple Cart Items at once (quantity and selling_plan)

[E_Zampo]

Hi,

In our Shop we have implemented a Bundle Logic bundling 2 to 8 products into one. In our Cart we show the bundle all in one Card with incredients. In order to change quantity and selling plan in our cart its necessary to change all items in one bundle. I dont know what exactly im doing wrong here but i always get bad requests.

let updateItems = {"id":"43603405996260:dbd0192e627f613dbadb11c7e9fd9a02", "quantity": 3, "selling_plan": 3613196516}

let updateItems2 = {items:[{'id':'436034260:dbd0192e627f61311c7e9fd9a02','quantity':3,'selling_plan':36136516},{'id':'43604534260:dbd0192e627f61311c7e9fd9a02','quantity':2,'selling_plan':3612136516}]}
updateCartItem(updateItems)
updateCartItem(updateItems2)

function updateCartItem (item) {
    fetch('/cart/change.js', 
      {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json'
      },
      body: JSON.stringify({
        updates:
        item
      })
    })
    .then(response => { 
      response.json();
      console.log(response)  
    } 
    )
.catch(console.error)


  }

 Many thanks 🙂

Cart Change Js is not working with bulk operations. The only Solution at this point is to delete and add them again.
