CORS headers not applied when serving `ElysiaFile`

[shaeberling]

What version of Elysia is running?

1.2.25

What platform is your computer?

Linux 5.10.240-238.966.amzn2.x86_64 x86_64 unknown (from oven/bun:1.2.19 Docker image)

What environment are you using

1.2.19

Are you using dynamic mode?

no

What steps can reproduce the bug?

Here's the relevant code from that path

const app = new Elysia({
  serve: {
    idleTimeout: 60,
  },
})
  .all("/healthz", healthz)
  .use(elysiaLogger("api"))
  .use(errorHandler())
  .use(isAxiomEnabled() ? elysiaTelemetry(SERVICE_NAME) : new Elysia())
  .use(
    cors({
      origin: [
        "https://domain.com",
        "https://another.com",
        "https://test.domain.com",
        "https://admin.domain.com"
      ].filter(Boolean),
    }),
  )
  .use(v1Routes)
  .use(webhookRoutes)
  .use(internalRoutes)
  // Serve the static frontend. These routes must come last.
  .use(frontendRoutes)
  .listen(process.env.PORT ?? 8000);



export const frontendRoutes = new Elysia()
  .get("/*", async ({ params }) => {
    return serveFile(params["*"]);
  });


async function serveFile(path: string) {
  try {
    const safePath = normalize(path);
    const fullPath = join(BASE_DIR, safePath);
    if (existsSync(fullPath) && statSync(fullPath).isFile()) {
      return file(fullPath);
}

What is the expected behavior?

CORS headers should be applied to the files served

What do you see instead?

No CORS headers added

Additional information

Our current, working, workaround is to take the ElysiaFile and build a normal Response object, taking the file contents as the body. When doing this, the CORS headers are being applied correctly.

Have you try removing the node_modules and bun.lockb and try again yet?

Yes
