import { WBAPIError } from './base-error.js';
/**
 * Error thrown when WB returns HTTP 409 with body `code: 'CustomsDeclarationIsRequired'`
 * — at least one assembly order in the request lacks a required customs-declaration
 * (ДТ, декларация на товары) number.
 *
 * Since **2026-08-18** (WB news):
 * - A customs-declaration number can be attached **only to assembly orders in `confirm` status**
 *   (via `sdk.ordersFBS.setCustomsDeclaration()`).
 * - **Armenia sellers** must attach a ДТ for items produced **outside the EAEU** when an order
 *   from Armenia is delivered to the Russian Federation.
 * - `POST /api/v3/orders/stickers` (`sdk.ordersFBS.createOrdersSticker()`) returns this 409
 *   when any requested order lacks a required ДТ — stickers cannot be obtained until it is attached.
 *
 * The raw WB response body (including any `data` payload with order identifiers WB may include)
 * is preserved on {@link CustomsDeclarationIsRequiredError.response}.
 *
 * @since 4.3.0
 * @see {@link https://dev.wildberries.ru/docs/openapi/orders-fbs} — Orders FBS API
 *
 * @example Narrowing with instanceof
 * ```typescript
 * import { CustomsDeclarationIsRequiredError } from 'daytona-wildberries-typescript-sdk';
 *
 * try {
 *   await sdk.ordersFBS.createOrdersSticker({ type: 'png' }, { orders: [123456] });
 * } catch (err) {
 *   if (err instanceof CustomsDeclarationIsRequiredError) {
 *     console.log('Attach a customs declaration number before printing stickers');
 *     console.log('Raw body:', err.response);
 *     // err is still instanceof WBAPIError — existing catch-all blocks still work
 *   }
 *   throw err;
 * }
 * ```
