Exceptions throw 404 rather than 500

[cecilcosta]

node.js version: v12.4.0

npm/yarn and version: npm 6.9.0

koa-router version: 3.2.0

koa version: 2.7.0

Code sample:

module.exports.mycall = async (ctx, next) => {
  const object = await ObjectFinder.find(ctx.request.body.id); // this object doesn't exits and an exception is thrown.
  object.date = new Date();
  await object.save()
  ctx.status = 204
};

Expected Behavior:

As there was an exception the response code should be 500

Actual Behavior:

Got a 404, which makes no sense.

Additional steps, HTTP request details, or to reproduce the behavior or a test case:

I have similar problem with koa-router (v. 7.4), koa(2.7) i am working with nodemailer, and catching 404 error before like mail sended for user, but want send 200 status after sending mail

`const feedback = async (ctx) => { const { company, username, phone, email, } = ctx.request.body;

// here get 404, but if written ctx.status = 200; it is ok, but not sense

const mailer = async () => { const transporter = await nodemailer.createTransport({ host: 'smtp.gmail.com', port: 587, secure: false, auth: { user: mailuser, pass: mailpass, }, });

const output = `
      <p>company: ${company}</p>
      <p>username: ${username}</p>
      <p>phone: ${phone}</p>
      <p>E-mail: ${email}</p>
`;
const info = await transporter.sendMail({
  from: username,
  to: email,
  subject: email,
  html: output,
});

console.log(info.messageId); return new Promise((res, rej) => { if (info.messageId.length > 0) { res(); return info; } rej(); return 0; }); };

mailer().then(() => { console.log('where is my OK status ??'); ctx.body = { status: 200, msg: 'ok', }; }); };`

Log in my console
