Python script as rc service on FreeBSD operating system

I have a Python script that I would like to run in a FreeNAS jail. It works without the service daemon, but I would like to start it as a service. I have created the following service script **/etc/rc.d/attendance**

#!/bin/sh

# PROVIDE: attendance
# REQUIRE: DAEMON
# KEYWORD: shutdown

. /etc/rc.subr

name=attendance
rcvar=attendance_enable

load_rc_config $name

: ${attendance_enable="NO"}


pidfile="/var/run/${name}.pid"
command="/root/Zkteco/app.py"
command_interpreter=/usr/local/bin/python
run_rc_command "$1"

I have also added **attendance_enable="YES"** under /etc/rc.conf. When I run **service attendance start** I receive

Starting attendance
limits: /root/Zkteco/app.py: No such file or directory
/etc/rc.d/attendance: WARNING: failed to start attendance

Even though the directory exists, I tried moving it from /etc/rc.d/attendance to /usr/local/etc/rc.d/attendance and it seems to work, but it never goes as a background process either and I have to Ctrl+C to stop it. Any recommendation? The script is a web application using FastAPI and Uvicorn, does it have anything to do with it? How can I see the logs of the service error trying to start. **Thing I’ve tried** I created a binary with pyinstaller --onefile from the script. And changed

#!/bin/sh
.
.
.
command="/usr/local/bin/app"
run_rc_command "$1

This change made the service start but again, it never goes to background.
