Missing async/await on ErrorHandlingMiddleware #195
Description
Hej love the package so far.
But have found that you do not really do promise for Error Handling Middleware the same way as you do other middleware.
This is what I think could help in that regard.
Suggestion: index.js
383. // Execute error middleware
384. for (const err of this._errors) {
385. if (response._state === 'done') break;
386. // Promisify error middleware
387. await new Promise(async (r) => {
388. let rtn = await err(e, response._request, response, () => {
389. r();
390. });
391. if (rtn) response.send(rtn); r();
392. });
393. }
394. // end forAs seen you could implement it the same way as you do for other middleware.
IF there is a reason for not do it this way I really wanna know.
