Can't return Blob directly

[strblr]

Hello,

The docs shows a demo of a Blob being returned as an object value.
When I try to return a Blob directly from a handler, it works for audio/ogg types but not text/plain.

I imagine this is because of the response's content type triggering different parsing mechanisms but still wondering if it's by design or if we're not supposed to return blobs directly.

Thanks.

It should works, I will check if it a bug I will fix

Hey @strblr are you using node or fetch adatpers, I just try on nextjs 15 return new Blob(['hello'], { type: 'text/plain' }) still works

[unnoq]

The latest version (beta 1.0.0) the algorithm has been changed, please make sure every @orpc packages have the same version, rm node_modules for sure

[strblr]

I'm using the fetch adapter with Bun. I'm on ^0.47.0 everywhere.
When returning new Blob([text], { type: "text/plain;charset=utf-8" }), I have undefined in the client.

[strblr]

Using the tanstack query integration, if it matters

[unnoq]

Please upgrade to latest version 0.48 or beta, and try again, I cann't create your errors, Can you help me create an MVP

[strblr]

Just inspected the request, the response has content type text/plain;charset=utf-8 and the payload is correct. So it seems client-side.

[strblr]

I'll update and keep you posted

[strblr]

Fails on 0.48 and beta 1. I can try and make a demo. Do you have a template by any chance?

[unnoq]

No for tanstack

Didn't manage to make the client talk to the server. If you wanna give it a try, I did most of the boilerplate.

I think I figured out, this bug related to https://developer.mozilla.org/en-US/docs/Glossary/CORS-safelisted_response_header
oRPC need Content-Disposition to know it is a file rather than normal text,

[unnoq]

For temporary, you need to config cors to make it can access Content-Disposition

[unnoq]

Config your CORSPlugin like this

const handler = new RPCHandler(router, {
  plugins: [
    new CORSPlugin({
      exposeHeaders: ['Content-Disposition'],
    }),
  ],
});

[strblr]

Thanks, as a temporary fix I'm just returning { blob } instead of blob. Will update when it's fixed

Follow this: #269

Should work in v1.0.0-beta.2
