[rabbitmq-discuss] Problem when hitting /api/queues in rabbitmq management API

[andrew chase]

I'm not sure whether I should be asking this question here, or if
there's a different path for communicating problems with the
rabbitmq-management plugin. I thought about opening an issue via
github, but it looks like the rabbitmq-managment committers are
already using mercurial for ticket tracking.

I have been really impressed with the management plugin, however, I am
having problems with making GET requests to the "/apis/queues" route.
When requesting that path I get back a 500 Internal server error. In
the rabbitmq log file the error is being logged as:

=ERROR REPORT==== 20-Dec-2010::16:21:58 ===
webmachine error: path="/api/queues"
{error,{exit,{json_encode,{bad_term,<0.16116.0>}},
            [{mochijson2,json_encode,2},
             {mochijson2,'-json_encode_proplist/2-fun-0-',3},
             {lists,foldl,3},
             {mochijson2,json_encode_proplist,2},
             {mochijson2,'-json_encode_array/2-fun-0-',3},
             {lists,foldl,3},
             {mochijson2,json_encode_array,2},
             {rabbit_mgmt_util,reply,3}]}}


I'm running a clean install of rabbitmq 2.2.0 with all the most recent
rabbitmq-management plugins. Here's the configuration details of the
stack:

/usr/sbin/rabbitmqctl status
Status of node 'rabbit at rabbit-server01' ...
[{running_applications,
     [{rabbit_management,"RabbitMQ Management Console","2.2.0"},
      {webmachine,"webmachine","1.7.0"},
      {rabbit_management_agent,"RabbitMQ Management Agent","2.2.0"},
      {amqp_client,"RabbitMQ AMQP Client","2.2.0"},
      {rabbit,"RabbitMQ","2.2.0"},
      {os_mon,"CPO  CXC 138 46","2.2.2"},
      {sasl,"SASL  CXC 138 11","2.1.6"},
      {rabbit_mochiweb,"RabbitMQ Mochiweb Embedding","2.2.0"},
      {mochiweb,"MochiMedia Web Server","1.3"},
      {crypto,"CRYPTO version 1","1.6"},
      {inets,"INETS  CXC 138 49","5.1"},
      {mnesia,"MNESIA  CXC 138 12","4.4.10"},
      {stdlib,"ERTS  CXC 138 10","1.16.2"},
      {kernel,"ERTS  CXC 138 10","2.13.2"}]},
 {nodes,[{disc,['rabbit at rabbit-server01','rabbit at rabbit-server02]}]},
 {running_nodes,['rabbit at rabbit-server01','rabbit at rabbit-server02']}]
...done.

Also, I'm running Erlang R13B01. Could that be the problem?

$ erl
