Cannot invoke method 'login'

[whitehat101]

I'm trying to get your code working, and I'm getting errors that probably because I made an incorrect assumption.

Brief:

The expected argument types are (com.riotgames.platform.login.AuthenticationCredentials) but the supplied types were (flex.messaging.io.amf.ASObject) and converted to (null).
Cannot invoke method 'login'
An Authentication object was not found in the SecurityContext

I'm starting the web server like this:
ruby ./lib/riot2json.rb USERNAME PASSWORD na1 3000 4.3.14_03_04_17_09

Where USERNAME is my login (not in-game) name, 3000 is the local port for the webserver to bind, and 4.3.14_03_04_17_09 is the current version string I copied from the upper left corner of the LoLClient. Should these values work?

A working configuration example in the README would be appreciated.

If you can help me get your project running, I'd love to contribute back.

My apologies for this issue! This was a pretty old project for when I first started doing ruby.

I had to edit rocketamf/pure/serializer.rb and append:
class_name = obj.type if obj.class == RocketAMF::Values::TypedHash

on line 357
I never got around to requesting a patch for that (I might have just had it wrong?) but this project had a quite a few issues if i recall.
