I am currently using the http module to perform a POST operation to a
remote API call and I'm trying to figure out the best way to handle error
situations where things don't quite go as planned. I thought I could use
the error event emitter but I have a situation where the server returns a
500 http status code but my code in the error event emitter never fires.
My question is what will cause the error event emitter to fire? Is a http
return code of 500 enough or is it looking for something else in the
response from the call? The snippet of the node code in question is listed
below. The res.statusCode shows a value of 500, but the console.log within
the error emitter never fires off. This is occuring on version 0.8.11.
Any guidance would be appreciated.
