Http requests fail in node.js v0.11

[analog-nico]

The following code succeeds in node.js 0.10.28:

var client = require('elasticsearch').Client();
client.indices.exists({
  index: 'fancyindex'
}).then(function (response) {
  // ...
});

However, in node.js v0.11.13 it fails.

I debugged it and found out that when calling node's http.request(...) inside the function HttpConnector.prototype.request an agent is passed with the request parameters that is somehow incompatible.

When I set reqParams.agent = undefined; before the this.hand.request(reqParams, ...) call then the request succeeds again. Probably, the forever-agent you are depending on is the culprit?

Possibly.

As 0.11 is unstable by definition, I haven't taken time to solve why it doesn't work. A quick look at the 0.11.13 docs imply that the Agent's in 0.11 serve the same purpose as forever-agent, so you could probably use this custom HTTP Connector if you would like to use KeepAlive connections and node 0.11

Thanks for the info.

FYI: The signature of agent.addRequest(...) as it is implemented by CustomForeverAgent.prototype.addRequest and called from the native http module changed from passing the arguments req, host, port (node.js v0.10) to passing just req, options (node.js v0.11). options actually is reqParams from your this.hand.request(reqParams, ...) call.

This breaking change is already known to the author of forever-agent.
