post-install-cmd not working in Google App Engine Flexible Environment

I am trying to update a file permission via composer's post-install-cmd but seems to me it is not working correctly though in the log it says the command executed correctly but when I log in to the VM it still show the incorrect permission.

This is what I have in /composer.json

"scripts": {
    "post-root-package-install": [
        "@php -r \"file_exists('.env') || copy('.env.example', '.env');\""
    ],
    "post-install-cmd": [
        "chmod -R 777 public\/external_package\/webmail\/data"
    ]
}

This is what I have in my /app.yaml

runtime: php
env: flex

service: webservice-dev

runtime_config:
  document_root: public
  whitelist_functions: phpversion,phpinfo

env_variables:
  # Environment variables.
  APP_NAME: 'Laravel App (Dev)'
  APP_ENV: dev
  # ...
  # ...

beta_settings:
  cloud_sql_instances: ""

automatic_scaling:
  min_num_instances: 2
  max_num_instances: 10
  cpu_utilization:
    target_utilization: 0.50

resources:
  cpu: 1
  memory_gb: 4

Here is the screenshot of Cloud Build

gcp file permission issue

And this is what I see in VM

dr-xr-x--- 1 root www-data  4096 Jan 28 19:18 data

I want this directory permissions to be 777 rather than 550

This is because App Engine always locks the document root path, for this reason the permissions are reverted.

Add this to your app.yaml

runtime_config:
  skip_lockdown_document_root: true

The option skip_lockdown_document_root: true will prevent permissions from being changed.
