Module to handle custom iq stanzas does not work with ejabberd-18.09

I am trying to move to ejabberd-18.09 from ejabberd-17.03. I have this module so that I can send custom iq stanzas to ejabberd.

Am I missing something or is there any change in the way it should be done in ejabberd-18.09?

The relevant part of the error:undef,[{mod_test_custom,process_local_iq. That is, the functionmod_test_custom:process_local_iqis undefined, most likely because themod_test_custommodule cannot be loaded. Where is the filemod_test_custom.beamlocated?

It is placed with the other .beam files of ejabberd i.e inside usr/local/lib/ejabberd-18.09/ebin folder. plus I have double checked it that it's entry is made in the modules section of ejabberd.yml
– abhishek ranjan
Nov 22 '18 at 10:02
That's strange, I would expect the module to be loaded automatically in that case...
– legoscia
Nov 22 '18 at 10:04
yes exactly, this is where it confuses me.

Ah, you're right! I misread the error message. The problem is that ejabberd callsmod_test_custom:process_local_iqwith one argument, but your function expects three arguments. Looks like it gets called with an#iq{}record, but not sure where that is defined...

I have followed these steps to register a custom iq https://github.com/processone/xmpp/issues/9 but still no luck.This is the element which I added in my xmpp/specs/xmpp_codec.spec file

Am I missing something or is there any change in the way it should be done in ejabberd-18.09?

The relevant part of the error:undef,[{mod_test_custom,process_local_iq. That is, the functionmod_test_custom:process_local_iqis undefined, most likely because themod_test_custommodule cannot be loaded. Where is the filemod_test_custom.beamlocated?

It is placed with the other .beam files of ejabberd i.e inside usr/local/lib/ejabberd-18.09/ebin folder. plus I have double checked it that it's entry is made in the modules section of ejabberd.yml

Ah, you're right! I misread the error message. The problem is that ejabberd callsmod_test_custom:process_local_iqwith one argument, but your function expects three arguments. Looks like it gets called with an#iq{}record, but not sure where that is defined...

Ah, you're right! I misread the error message. The problem is that ejabberd calls

The relevant part of the error:
undef,[{mod_test_custom,process_local_iq. That is, the functionmod_test_custom:process_local_iqis undefined, most likely because themod_test_custommodule cannot be loaded. Where is the filemod_test_custom.beamlocated?– legoscia

It is placed with the other .beam files of ejabberd i.e inside usr/local/lib/ejabberd-18.09/ebin folder. plus I have double checked it that it's entry is made in the modules section of ejabberd.yml

That's strange, I would expect the module to be loaded automatically in that case...

yes exactly, this is where it confuses me.
