TypeError: Cannot set property 'corked' of undefined

100% reproducible for me in v2.4.0. 2.3.2 is fine.

I'm using koa:

import serverless from 'serverless-http';
import Koa from 'koa';

const app = new Koa();

app.use(ctx => {
  ctx.body = 'Hello World';
});
module.exports.handler = serverless(app);

results in internal server error on AWS Lambda. Logs from lambda:

What version of Node?

[dougmoscrop]

oh, and version of Koa

[dougmoscrop]

Try 2.4.1, but I'd still like to know what version(s) as I wrote a test and could not reproduce it, probably because of what version of Koa I was using

[adamnoakes]

Node.js 12, i never tried 10. Koa version is 2.11

2.4.1 appears to be working 👍

[dougmoscrop]

okay great, sorry about that!

[adamnoakes]

No problem, thanks for patching so quickly.
