## ❌ Critical Issue

### POST /api/returns - Create Return
**Error**: `"Return item must have inventory_item_id"`

**Problem**: Validation incorrectly requires `inventory_item_id` for ALL return items, even quantity-based items.

**Impact**: **HIGH** - Blocks return functionality for non-UID tracked items

**Fix Required**: Make `inventory_item_id` optional in `server/modules/returns/validations/index.js`

---

## ⚠️ Response Structure Variations (Not Errors)

These APIs work correctly but return data directly in `.data` instead of `.data.{resource}`:

- **GET /api/payments/:id** - Returns `.data.{fields}` directly
- **GET /api/discounts/code/:code** - Returns `.data.{fields}` directly
- **GET /api/shifts/current** - Returns `.data.{fields}` directly
- **GET /api/shifts/:id** - Returns `.data.{fields}` directly
- **GET /api/customers/:id** - Returns `.data.{fields}` directly
- **GET /api/procurement/vendors/:id** - Returns `.data.{fields}` directly
- **GET /api/customers/search** - Returns `.data` as array directly

**Note**: Use `.data` directly when accessing fields, not `.data.{resource}`.
