AWS CodeDeploy not running hooks scripts - node.js

Question

I'm learning how to use CodePipeline and have problem with CodeDeploy for small testing node app. My target is to implement CD for large express + react app and I need to use hooks from AppSpec.yml.
For now everything else is working, files are copied etc, it just doesn't fire script. I started with BeforeInstall (delete process from pm2) and ApplicationStart (start app with pm2) hooks, but now I switched to using ApplicationStart with script to remove process from pm2 just to see if it works.
My AppSpec.yml:
version: 0.0
os: linux
files:
- source: /
destination: /home/ubuntu/api
permissions:
- object: /home/ubuntu/api/
owner: ubuntu
group: ubuntu
mode: "777"
# I use appStop.sh just to check if this works:
ApplicationStart:
- location: scripts/appStop.sh
runas: ubuntu
# I tried also running as root, still nothing
timeout: 60
appStop.sh:
#!/bin/bash
cd /home/ubuntu/api
pm2 delete 0
I tried many things, also running everything as root (though I prefer to use ubuntu user).
There are no ERRORs in log file in /var/log/aws/codedeploy-agent.
I can also see all files and scripts dir in reviev in /opt/codedeploy-agent/deployment-root/...
When I manually run appStop script in home dir it works.
It looks like CodeDeploy agent is just not running script.

Ok it seems I made it work.
First I cleaned codedeploy-agent data by removing /opt/deployment-root/<deployment droup id> dir and /opt/deployment-root/deployment-instructions
I also changed location, don't know if this helped, but had to do it since I decided to go with root user to make things easier. App is now in /var/www/api.
I also reinstalled all js software (node, pm2, npm) using sudo
My working AppSpec.yml:
version: 0.0
os: linux
files:
- source: /
destination: /var/www/api
permissions:
- object: /var/www/api/
mode: 775
type:
- file
- directory
hooks:
ApplicationStop:
- location: scripts/appStop.sh
runas: root
ApplicationStart:
- location: scripts/appStart.sh
runas: root
and working scripts:
appStop.sh:
#!/bin/bash
cd /var/www/api
sudo pm2 delete 0
appStart.sh:
#!/bin/bash
cd /var/www/api
sudo pm2 start server.js
