const oderSchema = z.object({
  id: z.number(),
  description: z.string(),
  quantity: z.number(),
});

type Order = z.infer<typeof oderSchema>;

export const handler = middy()
  .use(parser({ schema: oderSchema, envelope: sqsEnvelope }))
  .handler(async (event) => {
           // ^ event is inferred as Order[]
