Hi,

I’m trying to update the price of a line item that’s on a selling plan (recurring weekly delivery), but the price adjustment in CartTransform function is ignored.

Function output

{
  "operations": [
    {
      "update": {
        "cartLineId": "gid://shopify/CartLine/ccdebcaf-0eca-412b-8d62-2371ce5ba5e1",
        "title": "Product name",
        "price": {
          "adjustment": {
            "fixedPricePerUnit": {
              "amount": "100.00"
            }
          }
        }
      }
    }
  ]
}

I tried changing fixedPricePerUnit to recurringPricePerUnit, but that throws an output error.

I need to change the initial order price, afterwards I can edit the Subscription Contract. Is there any way I can achieve that? If not, are there any plans to add selling plan products support to CartTransform Functions?
