### Description
using KEMI API in Python v2.7.18 for Kamailio v5.6.2, I encounter error in
`ksr_onsend_route`, it always gives following error,
```
ERROR: app_python [python_support.c:154]: python_handle_exception(): apy_exec:
ksr_onsend_route((null)): Unhandled exception in the Python code:
TypeError: an integer is required
```
<!--
Explain what you did, what you expected to happen, and what actually happened.
-->
### Troubleshooting
Above error happens even if there is no code in this function and it returns success,
e.g.
``` python
...
def ksr_onsend_route(self, msg):
return 1
...
```
#### Reproduction
It happens always whenever `ksr_onsend_route` function exists in `kamailio` class in KEMI
python configuration for kamailio.
<!--
If the issue can be reproduced, describe how it can be done.
-->
#### Debugging Data
Nothing relevant in debug even with `debug=9` set.
<!--
If you got a core dump, use gdb to extract troubleshooting data - full backtrace,
local variables and the list of the code at the issue location.
gdb /path/to/kamailio /path/to/corefile
bt full
info locals
list
If you are familiar with gdb, feel free to attach more of what you consider to
be relevant.

#### Log Messages
<!--
Check the syslog file and if there are relevant log messages printed by Kamailio, add them
next, or attach to issue, or provide a link to download them (e.g., to a pastebin site).

#### SIP Traffic
<!--
If the issue is exposed by processing specific SIP messages, grab them with ngrep or save

### Possible Solutions
I suspect the problem is at low level (native code) of app_python module.
