Laravel not finding MessageBag class?

Question

Laravel

As for me, the obvious is not enough. From what side to solve the problem is not clear.
The following code works successfully on the laptop:

Route::get('test', function() {
    // print(phpinfo());
    $messageBag = new Illuminate\Support\messageBag();
  });

And on the server it fails with an error:

Class 'Illuminate\Support\messageBag' not found

The path to the file where the class is located is correct.
I tried uploading to two servers - the result is the same. Both servers on different Linux, laptop on Windows.
There's something I don't quite understand :)

Answer 1

I guess it doesn't work on Linux due to file system case sensitivity.
Correctly the class is called MessageBag.
