(err instanceof APIError) always returning false

[skoope]

in config/express.js :

else if (!(err instanceof APIError)) {
    const apiError = new APIError(err.message, err.status, err.isPublic);
    return next(apiError);
  }

is supposed to catch errors that aren't instanceof APIError and convert them, but this always return false : example :

const err = new APIError('Not found', 404, true);
console.log(err instanceof APIError) // false
console.log(err instanceof Error) // true

Which version of the boilerplate are you using?

[skoope]

version 1.0.0

I guess that's because of Babel.

You may need to use babel-plugin-transform-builtin-extend to make instanceof works as expected in Babel environment.

Take a look of this.
