Never mind, I have found the solution,

instead of,

KSR.async.task_group_route("replication_send", "rpl_send")

use this,

getattr(KSR, 'async').task_group_route("replication_send", "rpl_send")

That's because *async* is a python keyword and should not be used as variable or function name.

Thank you.

Hi,

I am trying to use *async* module functions in Python KEMI on Debian 13 with kamailio version 5.8.8,

Here is an example,

KSR.async.task_group_route("replication_send", "rpl_send")

However, it throws following exception,

kamailio[2927480]: ERROR: app_python3 [python_support.c:167]:

...

python_handle_exception(): mod_init: Unhandled exception in the Python code: File "/etc/kamailio/kemi.py", line 904 KSR.async.task_group_route("replication_send", "rpl_send") ^^^^^ SyntaxError: invalid syntax

This function works in kamailio.cfg but not in KEMI, even though it is documented at,

https://kamailio.org/docs/tutorials/devel/kamailio-kemi-framework/modules/#k...

Note: I tried to use other functions of same module and get similar error.

What is correct syntax to use this module's functions in KEMI Python? Please suggest.

Thank you.
