`vercel dev` error: Uncaught TypeError: r.read is not a function

[Noah Zoschke]

First time using deno + vercel. Thanks for the runtime. The examples out of the box aren't working for me

error: Uncaught TypeError: r.read is not a function
    const result = await r.read(b);
                           ^

I suspect bad timing... I'm using the latest vercel-deno@2.0.3 published on npm but the docs and recent PRs refer to v3 with breaking changes.

Ah! Also using oak@v11.1.0. The example with oak@v9.0.0 works, so investigating differences in that package now.

Having some success like this. I think there are two issues...

• vercel-deno@2.0.3 still requires ServerRequest
• oak@v11.1.0 handle isn't compatible

import { Application } from "https://deno.land/x/oak@v11.1.0/mod.ts";
import { ServerRequest } from "https://deno.land/std@0.106.0/http/server.ts";

const app = new Application();

app.use((ctx) => {
  ctx.response.body = "Hello World!";
});

export default async function (req: ServerRequest) {
  const res = await app.handle(req);
  req.respond({
    body: await res?.text(),
    headers: res?.headers,
  });
}

vercel-deno@3.0.0 has just been released. Please give it a try, and see the oak example which is working with the current version of Oak.
