[Freeswitch-users] mod_event_erlang and invalid process type

[Gerald Weber]

Hi all,

trying to learn erlang i tried to connect to freeswitch using mod_event_erlang and receive some events:

erlang shell:

[root at fstest ~]# erl -name test33 at freeswitch.besharp.at -setcookie ClueCon
Erlang R15B03 (erts-5.9.3.1) [source] [64-bit] [smp:2:2] [async-threads:0] [hipe] [kernel-poll:false]

Eshell V5.9.3.1  (abort with ^G)
(test33 at freeswitch.besharp.at)1> Pid = fsevents:start().
<0.46.0>
(test33 at freeswitch.besharp.at)2> fsevents:init('freeswitch at freeswitch.besharp.at').
{event,'ALL'}
(test33 at freeswitch.besharp.at)3>


Console output:

2012-12-31 13:18:36.900506 [DEBUG] handle_msg.c:301 ALL events enabled
2012-12-31 13:18:36.900506 [DEBUG] handle_msg.c:314 enable event ALL
2012-12-31 13:18:51.480577 [ERR] ei_helpers.c:274 Invalid process type 0! ((null),, <0.0.0>)
2012-12-31 13:18:51.480577 [ERR] ei_helpers.c:274 Invalid process type 0! ((null),, <0.0.0>)
2012-12-31 13:18:51.500492 [ERR] ei_helpers.c:274 Invalid process type 0! ((null),, <0.0.0>)

Can anyone tell me what i'm doing wrong ? Console log keeps saying invalid process type (until i kill the erlang process)
and i dont receive any events.

Erlang Version: 5.9.3.1
Freeswitch: latest HEAD from 2012-12-31

The fsevents module:

-module(fsevents).
-export([start/0, init/1, loop/0]).

start() ->
                Pid = spawn(?MODULE, loop, []),
                register(?MODULE,Pid),
                Pid.

init(Node) ->
                {foo, Node} ! {event, 'ALL'}.

loop() ->
                receive
                               stop ->
                                               ok;
                               _Anything ->
                                               io:format("received ~p~n", [_Anything]),
                                               loop()
                end.


The communication seems to work basically:


(test33 at freeswitch.besharp.at)4> {foo, freeswitch at freeswitch.besharp.at} ! {api, status, ""}.
{api,status,[]}
(test33 at freeswitch.besharp.at)5> receive Y -> Y after 1000 -> timeout end.
