EMG returns null value for err parameter in onerror_request hook in a custom plug-in

[csilsantos]

Using Apigee Edgemicro version 2.3.3 (latest release at this time), If I call an API proxy that exists in Apigee Cloud but this API proxy has an unavailable target endpoint, NONE of the "onresponse hooks" are called and the onerror_request is called.

However, in onerror_request: function(req, res, err, next) hook, the err parameter comes with NULL value, therefore its not possible to handle the error. This was previously discussed in the community forums, onerror_request and onerror_response hooks in custom plugins to handle errors .

Ex.: If I call:

curl -v http://localhost:8000/ping

where /ping as a unavailable target endpoint.

and in my plug-in, simply get the err parameter and print out:

onerror_request: function(req, res, err, next) {
  debug('plugin onerror_request ' + err);
  next();
}

i got the response in the EMG logs:

plugin:custom-test plugin onerror_request null

Thanks!

I'll take a look at this. Thanks.
