Where are sh scripts run from in BeforeInstall and AfterInstall in appspec.yml?

Question

Amazon Web Services

There is a repository on github. From there, using AWS CodeDeploy Pipelines, the code is deployed to an EC2 machine. I wrote the following in appspec.yml:

version: 0.0
os: linux
files:
  - source: /
    destination: /home/ec2-user/discord/
hooks:
  BeforeInstall:
    - location: stop.sh
      timeout: 60
      runas: user
  AfterInstall:
    - location: start.sh
      timeout: 60
      runas: user

start.sh and stop.sh are located directly in the repository, not in separate folders. When trying to deploy, BeforeInstall gives an error like "file not found"

LifecycleEvent - BeforeInstall
Script - stop.sh
[stderr]bash: /opt/codedeploy-agent/deployment-root/1f6e86fa-af22-4586-b715-9c393c86900e/d-VUFS9W9N4/deployment-archive/stop.sh: bin/bash/: bad interpreter: No such file or directory

I tried to write the full path in the location, it did not help.
