The error message indicates that you’re trying to modify a read-only field, specifically the gross_sales_money field under order.line_items. This field is calculated by Square and cannot be directly modified by a client.

When you’re trying to update an order, you should only include the fields that you want to change in the request body. If you want to remove a line item, you should not include the gross_sales_money field in your request.

If you want to remove a line item from an order, you should use the UpdateOrder endpoint and specify the line item to be removed in the fields_to_clear array. The value should be line_items.<uid>, where <uid> is the unique identifier of the line item you want to remove.

In your case, if you want to remove the last line item, your fields_to_clear array should look like this:

"fields_to_clear": [
    "line_items.AFOYDFJDJYHRUEF27BTD4NK7"
]

This tells Square to remove the line item with the uid AFOYDFJDJYHRUEF27BTD4NK7 from the order.
