[rabbitmq-discuss] erlang client problem (badarg in {amqp_channel, handle_regular_method, 3})

[Alexander Sviridov]

Hello!

I'm new to RabbitMQ (and Erlang too), trying to get message from
queue. Getting this:

=INFO REPORT==== 23-Mar-2010::11:24:47 ===
Negotiated maximums: (Channel = 0, Frame= 131072, Heartbeat=0)

=ERROR REPORT==== 23-Mar-2010::11:30:21 ===

summary:     Merge bug21949 into default

my code:
listen_loop(Channel, Q, Ticket) ->
  BasicConsume = #'basic.consume'{ticket = Ticket,
                                  queue = Q,
                                  nowait = true},
  ok
      = amqp_channel:call(Channel, BasicConsume),

  %% If the registration was sucessful, the consumer will
  %% be notified

  receive
        #'basic.consume_ok'{consumer_tag = Tag} -> ok
  end,
  receive
       {#'basic.deliver'{exchange  =  Exchange},
        Content}  ->
           #content{payload_fragments_rev  =  [Payload]}
            =  Content,
           io:format("Message  received:  ~p~n",  [Payload])
  end,

  listen_loop(Channel, Q, Ticket).


I'm doing something in a wrong way, I guess...

Any help will be appreciated, thank you!
