Class ‘IlluminateSupportfacadesHttp’ not found

My Laravel app was running successfully locally on my PC using WAMP server

PHP 7.4.0
Laravel 7.20.0
WAMP 3.2.0

When I deployed my app on a RedHat server,

PHP 7.4.9
Laravel 7.20.0
Appache 2.4.6
RedHat 7

I faced the below error when I make an HTTP request:

Error: Class 'IlluminateSupportfacadesHttp' not found in file /var/www/html/chatbot/app/Http/Controllers/BotController.php on line 25

The only difference is the PHP version

composer.json

{
    "name": "laravel/laravel",
    "description": "The Laravel Framework.",
    "keywords": ["framework", "laravel"],
    "license": "MIT",
    "type": "project",
    "require": {
        "php": "^7.2.5",
        "fideloper/proxy": "^4.2",
        "fruitcake/laravel-cors": "^1.0",
        "guzzlehttp/guzzle": "^6.3",
        "laravel/framework": "^7.0",
        "laravel/helpers": "^1.2",
        "laravel/tinker": "^2.0",
        "laravel/ui": "^2.0",
        "yajra/laravel-datatables-oracle": "^9.10"
    },
    "require-dev": {
        "filp/whoops": "^2.0",
        "facade/ignition": "^2.0",
        "fzaninotto/faker": "^1.9.1",
        "mockery/mockery": "^1.3.1",
        "nunomaduro/collision": "^4.1",
        "phpunit/phpunit": "^8.5"
    },
    "autoload": {
        .
        .

And please note that locally, i upgraded my laravel version from laravel 5 to laravel 7 from the beginning.

Do i have to install anything else on the server to make an HTTP request ?

Answer

Change IlluminateSupportfacadesHttp => IlluminateSupportFacadesHttp . The f in facade needs to be in uppercase.

File names in Linux are case sensitive while in Windows/NTFS file systems, it’s not. So, locally, it would not be a problem since your environment is Windows (assumed from WAMP).
