I deployed a PHP application with Laravel, and I need to change the permissions of some project folders to upload some files through the application. 

Here are the commands I need to run on the server:

chmod -R 775 storage
chmod -R 775 bootstrap/cache
chmod -R 775 public/uploads

Without running them, I cannot upload any files to the application. 

This is an urgent request, I need to resolve it as soon as possible as the operation of my company depends on this adjustment.

Attempts to solve the problem that were unsuccessful:

1. Add the environment variable "RAILWAY_RUN_UID=0"

2. Execute a .sh script containing the commands mentioned through package.json

Ex: 
"scripts": {
	"lint": "eslint ./resources/views/page",
	"dev": "vite",
	"build": "vite build && sh startup.sh",
	"clean": "vite clean",
	"watch": "gulp watch"
},

The content of startup script:
---------------------------------
#!/bin/bash

# Alterando as permissões das pastas
chmod -R 775 storage
chmod -R 775 bootstrap/cache
chmod -R 775 public/uploads

echo “Permissões atualizadas com sucesso!”
---------------------------------------------

The .sh script was indeed executed and I received the success log, but permission was still not granted to the directories.

Log: #15 7.557 “Permissões atualizadas com sucesso!”

-----------------------------------------------

I am using the default deploy with nickspacks, how can i solve this without using a Dockerfile?
