any help appreciated webhook will not execute .sh

[4mikedaniel-cloud]

When I run webhook as a service it will not execute my .sh If I run it not as a service it will execute webhook as expected.

stream1.sh

#!/bin/bash

/usr/bin/mpv udp://239.255.42.58:5004 --fullscreen 

--profile=low-latency

my webhook.service:

[Unit]
Description=adnanh/webhook service
After=network.target

[Service]
ExecStart=/usr/bin/webhook -hooks /home/mike/hooks/hooks.json -verbose
Restart=always
User=mike
Group=mike


[Install]
WantedBy=multi-user.target

My hooks.json: (trying multiple options)

[
  {
    "id": "input1",
    "execute-command": "/home/mike/hooks/./stream1.sh",
    "command-working-directory": "/home/mike/hooks",
    "pass-arguments-to-command":
  },
  {
    "id": "input2",
    "execute-command": "/home/mike/hooks/./stream1.sh",
  },
  {
    "id": "mpv",
    "execute-command": "/usr/bin/mpv udp://239.255.42.58:5004 --fullscreen --profile=low-latency",
    "pass-arguments-to-command":
  }
]

systemctl status webhook.service says it is executing but it does not:

incoming HTTP GET request from 192.168.1.96:19863

Try adding the -debug flag to your webhook command in the unit file. Where does your unit file live? Is it a system service or a user service (inside your user directory)?

I added -debug to webhook command

[Unit]
Description=adnanh/webhook service
After=network.target

[Service]
ExecStart=/usr/bin/webhook -debug -hooks /home/mike/hooks/hooks.json -verbose
Restart=always
User=mike
Group=mike


[Install]
WantedBy=multi-user.target

Seems it gave a little more info in

journalctl -u webhook

webhook.service is located in /usr/bin/

Should this be located somewhere else not in /usr/?

Thanks for the help!

[4mikedaniel-cloud]

Correction... webhook is located in /usr/bin/ and webhook.service is located in /etc/systemd/system

It looks like you left off a line or two from the end of the debug logs, but it may not matter.

I suspect that the systemd service is not allowed to access anything in your user home directory. You may need to turn off ProtectHome= in your unit file. See https://unix.stackexchange.com/questions/684068/systemd-protecthome-allowing-access-to-specific-home-directory.

PS - You can create code blocks in Markdown comments by using three backticks around your code.
