Help running commands through webhook (First time user)

[SammyWhamy]

So first of all, please bear with me, I'm fairly new to linux in general!

What I'm trying to achieve is this:
I push to GitHub
Github sends a request to my server
webhook processes this and runs the following script with the following errors:

# Running the first two right now to test if it's running in the right place and all
whoami # sammy 
pwd # /home/sammy/path

# The commands that actually matter
git pull git@github.com:SammyWhamy/repo.git # command output: git@github.com: Permission denied (publickey).
yarn install # yarn: not found
tsc # tsc: not found
pm2 restart 0 # pm2: not found

I believe I can solve the Git issue myself, maybe not with SSH but I can always just use https with credentials, the main issue is the not found

My config looks like this:

[
  {
    "id": "name-here",
    "execute-command": "/home/sammy/path/script.sh",
    "command-working-directory": "/home/sammy/path",
  }
]

I've been messing around with this for 2 days but I just can't figure out what is going wrong.
Running the script myself works fine, everything launches and the restart happens.
I'm currently running through cron, my cron setup looks like this:

@reboot webhook -hooks /home/sammy/hooks.json -verbose >> /home/sammy/logs/cron_webhook.log 2>&1

I've already tried other stuff such as supervisor (I can't get this to run as my user, so I end up getting the same output), but there's nothing I can get to work.

Update, I tried using the absolute paths to the executables:

#!/bin/sh

git pull # This works!
# These next 3 all return:
# /usr/bin/env: ‘node’: No such file or directory
/home/sammy/.nvm/versions/node/v16.7.0/bin/yarn install
/home/sammy/.nvm/versions/node/v16.7.0/bin/tsc
/home/sammy/.nvm/versions/node/v16.7.0/bin/pm2 restart 0 

Now I think it's good im getting a step further but I assume yarn is trying to call node which it in turn can't find? But I can't make yarn take the full path as far as I'm aware so I'm a bit lost again

Update 2, I fixed my issue!

What I ended up having to do was this:

export PATH=$PATH:/home/sammy/.nvm/versions/node/v16.7.0/bin # I also added the rest of my regular PATH but I think this is all that was needed

# Rest of script

Again, most likely this was a pretty stupid question but I'm glad I resolved it!

I am having the same issue. Can you explain me a little more about this? Where do I have to put the export command?

# FILE: redeploy.sh
#!/usr/bin/env bash
exec > /root/webhooks/output.log 2>&1
git fetch --all
git checkout --force "origin/master"

cd ./backend

yarn
yarn build
pm2 restart dist/apps/dashboard/main.js --name dashboard-api --update-env
