Experimenting with KEMI for the first time, I ran into a few issues and hoping someone has feedback.
kamailio 5.8.3
In the following python example, 'if ksr.is_method("ACK"):' should never be reached. Below is debug.
if not ksr.siputils.has_totag(): ksr.info("has to tag") sys.exit()
if ksr.is_method("ACK"): if ksr.tm.t_check_trans(): ksr.relay() sys.exit) else: sys.exit() ksr.sl.send_reply(404, "Not here") sys,exit()
..... DEBUG: app_python3s [apy3s_kemi.c:365]: sr_apy_kemi_exec_func_ex(): execution of method: siputils.has_totag DEBUG: siputils [checks.c:122]: has_totag(): no totag DEBUG: app_python3s [apy3s_kemi.c:368]: sr_apy_kemi_exec_func_ex(): execution of method: is_method DEBUG: app_python3s [apy3s_kemi.c:389]: sr_apy_kemi_exec_func_ex(): number of arguments: 1 DEBUG: app_python3s [apy3s_kemi.c:365]: sr_apy_kemi_exec_func_ex(): execution of method: sl.send_reply DEBUG: app_python3s [apy3s_kemi.c:389]: sr_apy_kemi_exec_func_ex(): number of arguments: 2 DEBUG: sl [sl.c:306]: send_reply(): reply in stateless mode (sl) .....
Second, here are a couple errors I have seen a few times but havent been able to identify the underlying issue, mainly hoping for more context on the meaning of 'execution of route type 1 with no name returned -1'.
ERROR: app_python3s [apy3s_kemi.c:146]: apy3s_exec_func(): error exception occurred
DEBUG: app_python3s [apy3s_kemi.c:230]: sr_kemi_config_engine_python(): execution of route type 1 with no name returned -1
Any input is appreciated.

Daniel, first check and fix sys.exit) -> sys.exit() and sys,exit() -> sys.exit()
Replace sys.exit() with `return` to avoid abruptly stopping the Kamailio process.
try it:
if not ksr.siputils.has_totag(): ksr.info("has to tag") return
if ksr.is_method("ACK"): if ksr.tm.t_check_trans(): ksr.relay() return else: return ksr.sl.send_reply(404, "Not here") return
regards!
Return yields the same results. I previously used return but changed to sys.exit() based on KEMI documentation page, I may have mis-interpreted the direction there. The comma was a typo in the email.
Thanks for the pointers. -dan ________________________________ From: Ricardo Castillo via sr-users sr-users@lists.kamailio.org Sent: Tuesday, November 12, 2024 18:00 To: sr-users@lists.kamailio.org sr-users@lists.kamailio.org Cc: Ricardo Castillo pkecastillo@gmail.com Subject: [SR-Users] Re: KEMI / Python Issues

I took a look at source for siputils module. This function returns -1 so the python syntax I'm using won't work here.
'if not' expects 0/false as return value. -dan

It might be necessary to return 1
using the same example:
if not ksr.siputils.has_totag(): ksr.info("has to tag") return
if ksr.is_method("ACK"): if ksr.tm.t_check_trans(): ksr.relay() return else: return ksr.sl.send_reply(404, "Not here") return 1
I was able to resolve the remaining errors by removing sys.exit() and replacing with return / return 1.
Any thoughts on what these debug lines are referring to? (what is route type and should name have a value?)

Daniel try using (try / except) for more debug or apply more verbose.
For it msg "execution of route type 1 with no name returned 1" use return -1 an try again.
try: # your code here except Exception as e: ksr.err(f"Exception occurred: {str(e)}") return
regards Richard
There are no exceptions raised, that output is only in kamailio debug. Was just curious what its meaning was.
