MongooseIM HTTP API returns 500 Internal Server Error

[jasl]

MongooseIM version: 3.3.0 Installed from: source Erlang/OTP version: Erlang/OTP 21 [erts-10.3.2] [source] [64-bit] [smp:12:12] [ds:12:12:10] [async-threads:1] [hipe] [dtrace]

I'm trying MongooseIM HTTP API for example simply browse http://localhost:8088/api/contacts from chrome, then I got 500 Internal Server Error

At MongooseIM side, the log shows

23:19:41.164 [error] CRASH REPORT Process <0.1418.0> with 0 neighbours crashed with reason: no match of right hand value [] in mongoose_api_admin:to_json/2 line 159

I also tried http://localhost:8088/api/users got the same error, but http://localhost:8088/api/commands works great.

[arcusfelis]

From code:

to_json(Req, #http_api_state{command_category = Category, bindings = B} = State) ->
    Cmds = mongoose_commands:list(admin, Category, method_to_action(<<"GET">>)),
    Arity = length(B),
    [Command] = [C || C <- Cmds, mongoose_commands:arity(C) == Arity], % line 159
    process_request(<<"GET">>, Command, Req, State).

There is no api/users command configured, probably because of misconfiguration. Please, include listen block of mongooseim.cfg configuration file, if you are still feeling, that it's a bug and not misconfiguration.

Some configuration documentation can be found here: https://mongooseim.readthedocs.io/en/latest/advanced-configuration/Listener-modules/#http-based-services-bosh-websocket-rest-ejabberd_cowboy

You can also generate a development release using make mim1 and check the config example _build/mim1/rel/mongooseim/etc/mongooseim.cfg, it should have the cowboy listeners configured correctly.

It should look something like this:

  { 8089 , ejabberd_cowboy, [
      {num_acceptors, 10},
      {transport_options, [{max_connections, 1024}]},
      {protocol_options, [{compress, true}]},
      {ssl, [{certfile, "priv/ssl/fake_cert.pem"}, {keyfile, "priv/ssl/fake_key.pem"}, {password, ""}]},
      {modules, [
          {"_", "/api/sse", lasse_handler, [mongoose_client_api_sse]},
          {"_", "/api/messages/[:with]", mongoose_client_api_messages, []},
          {"_", "/api/contacts/[:jid]", mongoose_client_api_contacts, []},

          {"_", "/api/rooms/[:id]/messages",    mongoose_client_api_rooms_messages, []}
      ]}
  ]},

{"_", "/api/rooms/:id/users/[:user]", mongoose_client_api_rooms_users, []} is the module you try to access.

@arcusfelis

Here's my configuration, it should be generated on make rel and I didn't modify it, I only tried http (port 8088)

  {{8088, "127.0.0.1"}, ejabberd_cowboy, [
    {num_acceptors, 10},
    {transport_options, [{max_connections, 1024}]},
    {modules, [
      {"localhost", "/api", mongoose_api_admin, []}
    ]}
  ]},

I've read the doc, it said mongoose_api_admin - REST API for admin commands. Exposes all mongoose_commands. It expects one optional argument that I think I'm not misconfigured.

[jasl]

But I'm not familiar with Erlang and MongooseIM, so I'm not sure anything

[jasl]

I've updated my configuration as yours @arcusfelis

  {8088, ejabberd_cowboy, [
    {num_acceptors, 10},
    {transport_options, [{max_connections, 1024}]},
    {modules, [
      % {"_", "/api", mongoose_api_admin, []},
      {"_", "/api/sse", lasse_handler, [mongoose_client_api_sse]},
      {"_", "/api/messages/[:with]", mongoose_client_api_messages, []},
      {"_", "/api/contacts/[:jid]", mongoose_client_api_contacts, []},
      {"_", "/api/rooms/[:id]",    mongoose_client_api_rooms, []},
      {"_", "/api/rooms/[:id]/config",    mongoose_client_api_rooms_config, []},
      {"_", "/api/rooms/:id/users/[:user]",    mongoose_client_api_rooms_users, []},
      {"_", "/api/rooms/[:id]/messages",    mongoose_client_api_rooms_messages, []}
    ]}
  ]},

still got error, but reason is different

20:16:56.924 [error] CRASH REPORT Process <0.1398.0> with 0 neighbours crashed with reason: no match of right hand value error in mongoose_client_api:check_password/2 line 114

I attached my full mongooseim.cfg, XMPP works great, but got problem on MongooseIM API

%%%               ejabberd configuration file
%%%
%%%'

%%% The parameters used in this configuration file are explained in more detail
%%% in the ejabberd Installation and Operation Guide.
%%% Please consult the Guide in case of doubts, it is included with
%%% your copy of ejabberd, and is also available online at
%%% http://www.process-one.net/en/ejabberd/docs/

%%% This configuration file contains Erlang terms.
%%% In case you want to understand the syntax, here are the concepts:
%%%
%%%  - The character to comment a line is %
%%%
%%%  - Each term ends in a dot, for example:
%%%      override_global.
%%%
%%%  - A tuple has a fixed definition, its elements are
%%%    enclosed in {}, and separated with commas:
%%%      {loglevel, 4}.
%%%
%%%  - A list can have as many elements as you want,
%%%    and is enclosed in [], for example:
%%%      [http_poll, web_admin, tls]
%%%
%%%    Pay attention that list elements are delimited with commas,
%%%    but no comma is allowed after the last list element. This will
%%%    give a syntax error unlike in more lenient languages (e.g. Python).
%%%
%%%  - A keyword of ejabberd is a word in lowercase.
%%%    Strings are enclosed in "" and can contain spaces, dots, ...
%%%      {language, "en"}.
%%%      {ldap_rootdn, "dc=example,dc=com"}.
%%%
%%%  - This term includes a tuple, a keyword, a list, and two strings:
%%%      {hosts, ["jabber.example.net", "im.example.com"]}.
%%%
%%%  - This config is preprocessed during release generation by a tool which
%%%    interprets double curly braces as substitution markers, so avoid this
%%%    syntax in this file (though it's valid Erlang).
%%%
%%%    So this is OK (though arguably looks quite ugly):
%%%      { {s2s_addr, "example-host.net"}, {127,0,0,1} }.
%%%
%%%    And I can't give an example of what's not OK exactly because
%%%    of this rule.

@jasl ,

I think even previous configuration (default one) should work without any issues as the commands you're trying to use are standard (see mod_commands module). The issue you initially faced is that both /api/contacts/[:jid] and /api/users/[:jid] require JID of user for which you're running the command. The HTTP path /api/contacts doesn't exists - you should call /api/contacts/john@snow.com instead.

EDIT:

I just checked and I can actually confirm - after enabling {"localhost", "/api", mongoose_api_admin, []} HTTP module, and after adding john@snow.com user, I do get HTTP 200 code after calling http://localhost:8088/api/contacts/john@snow.com.

I just tried as your suggest, it works! Thank you!

BTW, I mistype a wrong account then I got 500 internal error with

That's should be 404, I think I should open an issue about this
