arch linux + I3wm, script not working

I am a happy user of Arch Linux and i3-wm, but I have one problem: all binds work except for systemctl start/stop bluetooth.service.

The point was to turn Bluetooth on and off, connect headphones when turning it on. The script itself works if you run it in the terminal.

I set chmod +x for this script.

An exception is set in sudoers:

test_user ALL=(ALL) NOPASSWD: /usr/bin/systemctl stop bluetooth.service

test_user ALL=(ALL) NOPASSWD: /usr/bin/systemctl start bluetooth.service

test_user ALL=(ALL) NOPASSWD: /usr/bin/systemctl is-active bluetooth.service

bash script:

#!/bin/bash

DEVICE="34:11:01:B3:BC:47"

if sudo systemctl is-active bluetooth.service; then

sudo systemctl stop bluetooth.service

else

sudo systemctl start bluetooth.service

sleep 1

echo -e "agent on\ndefault-agent\nconnect $DEVICE\nquit" | bluetoothctl

sleep 2

fi

I3 config

bindsym $mod+b exec bash ~/my_scripts/bluetooth_toggle.sh
#bindsym $mod+b exec bash ~/my_scripts/bluetooth_toggle.sh - not working too
#bindsym $mod+b exec bash ~/my_scripts/bluetooth_toggle.sh - not working too

But when I set Firefox to open in the script for testing, it opened, so the problem is probably in the script itself.

Also, after several launches, faillock kicked in, meaning a password was required. I don't know what's wrong.
