Requested string is longer than available data

[bob1983]

I have read Mike Parks stickied post re: using the same ES version for client and server. I am using Electroserver v4.0.6 on both client and server, the server is running in a Linux environment and I am using the Actionscript 2 API on the client.

My problem arises when I attempt to send a pluginRequest from the client. Code snippet below:

public function sendMessage(plugin:String, command:String, parameters:Array, ignored:String):Void {
var values:EsObject = new EsObject();
values.setString("cmd", command);
values.setInteger("len", parameters.length);

trace("the esObject: " + values.toString());

var request:PluginRequest = new PluginRequest();
request.setPluginName("game");
request.setEsObject(values);

_es.send(request);


Here is the debug output on the client:
-- the esObject: {EsObject:
cmd:string = game
len:integer = 1
0:string = 23
}
-- [INFO] --> Sending :: conId: 0
-- [INFO] PluginRequest: C 1 3game0113113cmd13test013len111110undefinedundefine d23
-- [INFO] <-- Receiving :: conId: 0
-- [INFO] GenericErrorResponse
-- [INFO] Error occurred
-- [INFO] PluginRequest
-- [INFO] GenericError
-- [INFO] --connection closed-- id: 0


Here is the server stack trace:

When you compiled your client, did you use the API found here? There were some bugs in the API that comes when you install 4.0.6.

[bob1983]

Ah I forgot to mention that, but yes I am using the AS2 API provided in that link

[bob1983]

One thing, I'm not sure if this is relevant or not, i noticed in the debug line:

[INFO] PluginRequest: C 1 3game0113113cmd13test013len111110undefinedundefine d23

the undefinedundefined at the end of the message, perhaps this is significant

[tcarr]

Is the plugin you are trying to send the message to a server level plugin or a room plugin? If a server level plugin, you might want to add a logging line to the init method of it, then check the ES4 log to make sure it initializes. If it's a room plugin, you have to add the roomId and zoneId to the plugin request.

[bob1983]

It is a server level plugin, and it initializes without any hiccups

[tcarr]

Since TEXT protocol is the default, try removing this line and recompiling:
_es.setProtocol(Protocol.TEXT);

if that doesn't fix it, I'll need to build a similar client and play with it to see if it is a bug in the API that needs fixing. We don't have very many people using AS2 with ES4.0.6.

[bob1983]

Tried that, still no luck

[tcarr]

Ok, I'll work on it tomorrow and let you know if I reproduce it or not. Exactly which version of ES4 are you using? Straight 4.0.6 or one of the patches? Because I don't think I have an unpatched one left.

Interesting, I am using ElectroServer_4_0_6_unix.tar.gz, but when i start it up it says:

Starting ElectroServer 4.0.7-a3
Go to http://www.electro-server.com/ for the newest version.

So I was wrong when I said 4.0.6 as it appears to be 4.0.7...
