Remove Order line Item using update Api

Questions

"fields_to_clear": [
    "line_items.AFOYDFJDJYHRUEF27BTD4NK7"
]

I believe this is incorrect, as array access is needed. This is the correct format:

"fields_to_clear": [
    "line_items[AFOYDFJDJYHRUEF27BTD4NK7]"
]

However, when attempting to remove a line item on an order with voided payments this still causes issues. I am experiencing a similar issue with my request:

I am sending this sparse json object to the update_order endpoint, and expect line item uid_1 to be removed:

{
  "order": {
    "line_items": [
      {
        "quantity": "1",
        "uid": "uid_1",
        "note": "",
        "catalog_object_id": "id_1",
        "modifiers": [],
        "applied_taxes": [
          {
            "uid": "applied_tax_1",
            "tax_uid": "tax_1"
          }
        ],
        "applied_discounts": [
          {
            "uid": "applied_discount_1",
            "discount_uid": "discount_1"
          }
        ]
      },
      {
        "quantity": "1",
        "uid": "uid_2",
        "note": "",
        "catalog_object_id": "id_2",
        "modifiers": [],
        "applied_taxes": [
          {
            "uid": "applied_tax_2",
            "tax_uid": "tax_2"
          }
        ],
        "applied_discounts": [
          {
            "uid": "applied_discount_2",
            "discount_uid": "discount_2"
          }
        ]
      }
    ],
    "taxes": [
      {
        "uid": "tax_1",

      },
      {
        "uid": "tax_2",
        "name": "Tax 2",
        "type": "ADDITIVE",
        "percentage": "4",
        "scope": "LINE_ITEM"
      }
    ],
    "discounts": [
      {
        "uid": "discount_1",
        "scope": "LINE_ITEM",
        "type": "FIXED_AMOUNT",
        "name": "Discount",
        "amount_money": {
          "amount": 50,
          "currency": "USD"
        }
      },
      {
        "uid": "discount_2",
        "scope": "LINE_ITEM",
        "type": "FIXED_AMOUNT",
        "name": "Discount",
        "amount_money": {
          "amount": 25,
          "currency": "USD"
        }
      }
    ],
    "fulfillments": [
      {
        "type": "PICKUP",
        "uid": "order_uid",
        "pickup_details": {
          "recipient": {
            "customer_id": "customer_1"
          },
          "is_square_pickup_order": true,
          "pickup_at": "2025-01-01T00:00:00+00:00",
          "prep_time_duration": "PT5M"
        }
      }
    ],
    "version": 17
  },
  "fields_to_clear": [
    "line_items[uid_1]"
  ],
  "idempotency_key": "idempotency_key"
}

However, I get this error response:

{
  "code": "INVALID_VALUE",
  "detail": "Read-only field is calculated and cannot be set by a client.",
  "field": "order.line_items[uid_1].gross_sales_money",
  "category": "INVALID_REQUEST_ERROR"
}

I am not touching this calculated field, I am removing the line item it is attached to. Given that the previous payments have been voided, I would expect this to work without issue, but that is not the case.

Please advise. Currently my workaround will be to recreate this order entirely, because I am functionally unable to update it at all once a payment is attempted (and failed)
