app_audiocodes Error: Cannot find module 'filters/filter_app_audiocodes'

[myrcinos]

Hi,
I have followed the documentation and installed the app_audiocodes filter. However, when I try to run the paStash with the recommended config file it does not work. In debug mode paStash displays the following error:

I use the following config file:

input {
udp {
host => 0.0.0.0
port => 514
type => syslog
}
}

filter {
app_audiocodes{
#version => '7.40A.100.114'
version => '7.20A.256.396'
debug => false
autolocal => true
ini => '/tmp/audiocodes.ini'
}
}

output {
stdout{}
if [rcinfo] != 'undefined' {
hep {
host => '127.0.0.1'
port => 9060
hep_id => 2222
}
}
}

The INI file is in the /tmp folder.
Here is my npm and node version:
node -v
v18.13.0
npm -v
9.2.0
myrcin@ZabbixSRV:/opt/pastash$

Also during the installation of the app_audiocodes I got the following warnings:

What am I doing wrong? Even though, paStash seems to be running, it does not send any data. Any help is highly appreciated.

[Dletta]

@myrcinos Please execute pastash from /usr/lib/node_modules/@pastash/pastash folder and see if it starts then

[myrcinos]

I don't have a folder node_modules. However, I don't think this is the cause of the problem because when I start paStash with a config that don't have app_audiocodes, everything is fine.

[lmangani]

@myrcinos pastash plugins are installed as globals, and work best when pastash is too

npm install -g @pastash/pastash @pastash/filter_app_audiocodes

then simply run the installed pastash command with your config recipe

pastash --config_file=/path/to/pastash_audiocodes.conf

[myrcinos]

@lmangani
Here are the commands I used to install pastash and audiocodes filter:

sdudo npm install --unsafe-perm -g @pastash/pastash
sudo npm install --unsafe-perm -g @pastash/pastash @pastash/filter_app_audiocodes

I am not linux expert but -g means that they both have been installed as globals, right?

Here is the list of npm modules installed as globals. Does it look ok?

myrcin@ZabbixSRV:~$ sudo npm list -g
[sudo] password for myrcin: 
/usr/local/lib
├── @pastash/filter_app_audiocodes@1.1.5
├── @pastash/filter_app_sonuslog@1.0.13
├── @pastash/pastash@1.0.80
└── hepgen.js@1.0.9

Then, when I listed non-global modules I found multiple errors (please see below). How can I fix this. I thought that all dependencies would be installed while installing a module. Isn't that the case?

This part is a warning and if you look at the line below, the module does get loaded successfully.

Once you start pastash, you should see logs being emitted from the stdout plugin. If you simply see nothing, then you must not be sending to port 514 correctly. (Some systems don't allow these low ports, you can try doing 5514 and seeing if traffic appears then)
