/*
  Warnings:

  - You are about to drop the column `type` on the `sale_invoice_tsp_attempts` table. All the data in the column will be lost.
  - A unique constraint covering the columns `[ref_id]` on the table `sales_invoices` will be added. If there are existing duplicate values, this will fail.
  - Added the required column `type` to the `sales_invoices` table without a default value. This is not possible if the table is not empty.
