Lumen request all, input, file null - api

Question

I have a really weird problem. I've search already the whole web for the solution and found nothing.
I am not newbie in PHP.
I use Lumen in my application. To send the data I use Postman.
The problem is:
$request->file() and $request->allFiles() returns NULL.
But if I use PHP $_FILES then it shows all.
Route:
$router->post('/import/create', 'CalendarController#importCreate');
Controller:
public function importCreate(Request $request)
{
// Get uploaded CSV file
$files = $request->allFiles();
return response($files);
}
This is what I get back:
{
"files": [
{}
]
}
(empty json array)
But if I do like this:
return response($_FILES);
Then it works:
{
"files": {
"name": [
"logo.png"
],
"type": [
"image/png"
],
"tmp_name": [
"/tmp/phpjcjN4q"
],
"error": [
0
],
"size": [
7278
]
}
}
What we can exclude::
I use good Request import:
use Illuminate\Http\Request;
php.ini settings are OK:
The file I tried to upload has only 7KB, so its not the problem.
I use POST, and not PUT, so its not the problem.
Postman Request:
What I also noticed that $request->all() and $request->input() both returns also NULL, even if I post anything.
As I said I am not newbie in this, and I really appreciate your help.
Anyone got any clue?
Thanks in advance.

Ok, it has been fixed somehow. Don't know how, don't know when.
I updated composer dependencies with composer update but I'm not sure if that was the case.
