404 Could not initialize OMEMO support

[JLueke]

MongooseIM version: 3.6.2
Installed from: using the docker image
docker run -d -t -h mongooseim-1 --name mongooseim-1 -p 5222:5222 -p 5280:5280 -v $(pwd)/mongooseim-1:/member mongooseim/mongooseim:3.6.2
Where the folder mongooseim-1 only contains a slightly modified mongooseim.cfg (see comment below).
Erlang/OTP version: ?

My goal is to use encrypted chats with Converse JS and MongooseIM.

When I login a user with Converse JS, it tries to initialize OMEMO support but following error is shown in the browser console.

ERROR: <iq xmlns="jabber:client" from="alice@localhost" to="alice@localhost/converse.js-94611691" id="ebf5b37f-abe0-4834-9bd7-626285b25677:sendIQ" type="error"><error code="404" type="cancel"><item-not-found xmlns="urn:ietf:params:xml:ns:xmpp-stanzas"/></error><pubsub xmlns="http://jabber.org/protocol/pubsub"><items node="eu.siacs.conversations.axolotl.devicelist"/></pubsub></iq>

I've followed the Getting Started guide (with the exception that I used the docker image) and used the example config for mod_pubsub (without rdbms as backend).

I've already had a look at #2215 (tested with the provided config there) but I wasn't able to get it to work.

My current configuration for mongooseim.cfg is

%%%
%%%               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.

Hi @JLueke

I was able to turn on OMEMO in Converse.js with the MIM configuration you've provided. The error you've pasted doesn't mean that encryption is not supported. It is reported only on the first login of a user, because it is caused by a lack of OMEMO server-side data, which is populated by the client.

However I noticed there is some bug in OMEMO implementation in Converse.js which essentialy breaks the encryption after first message. My JS skill is insufficient to debug why the app throws strange errors about invalid identity. Please submit an issue report on Converse.js GitHub.

[JLueke]

@fenek thanks for testing and the explanation

the problem regarding "Identity key changed" already has some issues in ConverseJs so, I'll close this issue and add the solution afterwards, if I find one for that problem
