Does not work in combination with longjohn

[Gajus Kuizinas]

When used in combination with https://github.com/mattinsler/longjohn, produces no stack trace.

Extending Error object directly:

/Users/gajus/Documents/dev/gajus/mightyql/dist/index.js:86
    throw new _errors.NotFoundError();
          ^
Error: Resource not found.

Extending es6-error:

/Users/gajus/Documents/dev/gajus/mightyql/dist/index.js:86
    throw new _errors.NotFoundError();
          ^
NotFoundError: Resource not found.

This is a major bummer, because it makes it impossible to debug code that uses setTimeout, setImmediate, nextTick.

[Ben Youngblood]

Can you provide a simple example that causes this? Using node v7.7.4, the following script gave correct-looking output (I also tried simpler cases with just setTimeout, nextTick):

require('longjohn');
const { EventEmitter } = require('events');
const ExtendableError = require('es6-error');

class NotFoundError extends ExtendableError {}

class MyEE extends EventEmitter {
  emitErr() {
    this.emit('error', new NotFoundError('not found'));
  }
}

let x = new MyEE();

function causeAnErrorSoon() {
  setTimeout(function() {
    x.emitErr();
  }, 500);
}

causeAnErrorSoon();

Output:

/Users/bjy/workspace/es6-error/test.js:9
    this.emit('error', new NotFoundError('not found'));
                       ^
NotFoundError: not found

I think I rushed to report this issue. There is something low level going on that I haven't managed to isolate yet. Sorry.

Closing this for now.

I think I rushed to report this issue. There is something low level going on that I haven't managed to isolate yet. Sorry.

I am not even able to get the expected stack traces with:

console.log( "new Error('test').stack", new Error('test').stack );

just before throwing the error.

No worries! Feel free to reopen if it ends up being an issue with es6-error.
