req.emit('close');

When an HTTP request fails with an error, req.emit is not a function. I can reproduce in our application, but having difficulty creating a minimum sample. This is a call against an HTTPS endpoint that is returning a 500 error.

TypeError: req.emit is not a function
at TLSSocket.socketCloseListener (_http_client.js:271:7)
at emitOne (events.js:101:20)
at TLSSocket.emit (events.js:188:7)
at TCP._handle.close as _onclose

@carbonrobot we should try to replicate the problem. It seems tricky enough and we need to add a unit test anyway.

Would you mind trying to open a TLS socket against an HTTPS endpoint, and then close the socket? Maybe it's a TLS connection being dropped before any data is transferred.

@mcollina will do. I'm working on extracting the relevant code to make a minimal sample.

Root cause was the following issue. Closing at not related to Nodejs.
