Heads up! In the latest version of Oak, the value property on the request body was changed to be asynchronous and now returns a Promise.
If you're using the latest versions of Deno and Oak, you'll want to update the following:
const body = await ctx.request.body(); launches.addOne(body.value);
To:
const body = await ctx.request.body().value; launches.addOne(body);
That wasn't too bad! I'll see you back in the videos!
