In addition to redirecting, this bug also occurs when returning raw Response objects:

import { Elysia } from "elysia";

new Elysia()
  .get("/", () => "yay")
  .get("/redirect", ({ cookie: { name, name2 }, set }) => {
    name.value = 'value'
    name2.value = 'value2'

    return new Response('yay')
  })
  .listen(8080);

@SaltyAom, the main cause is that this function returns a Headers object:

elysia/src/handler.ts

Line 68 in 968650b

export const parseSetCookies = (headers: Headers, setCookie: string[]) => {

elysia/src/handler.ts

Lines 152 to 153 in 968650b

	set.headers = parseSetCookies(
	new Headers(set.headers) as Headers,

which cannot be used in such a spreading operation:

elysia/src/handler.ts

Line 201 in 968650b

const inherits = { ...set.headers }

inherits is allways {}

---

Is this parsing step even needed?
