13 |
* Bridges a v1 controller's ResponseEntity into the v2 ApiResponse envelope.
|
|
|
14 |
*
|
|
|
15 |
* Fix for silent-success bug: v1 code often signals validation failure by
|
|
|
16 |
* returning {@code responseSender.badRequest(payload)} — a 4xx response
|
|
|
17 |
* whose body carries context (e.g. cart with price-changed messages from
|
|
|
18 |
* {@code OrderController.createOrder}). The previous version blindly wrapped
|
|
|
19 |
* everything as {@code ApiResponse.success} + 200, so the React client
|
|
|
20 |
* treated a rejected order as a placed order and navigated to "Order
|
|
|
21 |
* Placed!" while no transaction was written. We now preserve the v1 status
|
|
|
22 |
* so axios rejects and the caller's catch-block runs.
