upload file on s3 with quasar vue (frontend) and laravel 9 (backend)

Question

I'm building a platform and I need to upload resources (pdf, images etc) on amazon s3 bucket. Frontend is made with quasar vue, backend with Laravel 9. The idea is to send file from frontend to backend and upload file on s3 with laravel.

The problem is that nothing happens, my s3 bucket remains empty with no errors or exceptions.

I'm not sure if the problem is sending file from frontend to backend or on the upload from laravel to s3 bucket.

I use q-uploader (but I think is not too different with quasar file-picker). Here's frontend code

<template>
  <q-page class="q-pa-sm">

    <q-uploader :factory="uploadFile"/>

  </q-page>
</template>

<script>
  import { api } from 'src/boot/axios';

  export default {
    methods: {
      uploadFile(f){
        var fileModel = f[0]
      
        const fileData = new FormData()

        fileData.append('file', fileModel)

        api.post('/api/resources/file', fileData, {
          headers: {
            'Content-Type': 'multipart/form-data'
          }
        })
        .then(res=>{
          console.log(res)
        })
      }
    }
  }
</script>

I made my API on api.php (and I'm sure middleware is not the problem)

Route::prefix('resources')->group(function(){

  /*
   * other APIs 
   */

  Route::post('/file',[ResourceController::class, 'postResourceFile'])->middleware('roles:1|2|3');

});

In laravel I've got a controller called ResourceController.php with this function

public function postResourceFile(Request $request){

  if($request->hasFile('file')){

    $file = $request->file('file');
    $name=time().$file->getClientOriginalName();
    $filePath = 'resources/' . $name;

    Storage::disk('s3')->put($filePath, file_get_contents($file));

    $response = [
      'file' => $file,
    ];
  } else {
    $response = [
      'message' => 'no file'
    ];
 }
 return response($response, 200);
}

In Laravel filesystems.php I didn't change original configuration

        's3' => [
            'driver' => 's3',
            'key' => env('AWS_ACCESS_KEY_ID'),
            'secret' => env('AWS_SECRET_ACCESS_KEY'),
            'region' => env('AWS_DEFAULT_REGION'),
            'bucket' => env('AWS_BUCKET'),
            'url' => env('AWS_URL'),
            'endpoint' => env('AWS_ENDPOINT'),
            'use_path_style_endpoint' => env('AWS_USE_PATH_STYLE_ENDPOINT', false),
        ],

And here's my .env AWS configuration.

AWS_ACCESS_KEY_ID=myID
AWS_SECRET_ACCESS_KEY=myKey
AWS_DEFAULT_REGION=eu-central-1
AWS_BUCKET=myBucket
AWS_USE_PATH_STYLE_ENDPOINT=false
AWS_URL=http://s3.eu-central-1.amazonaws.com/myBucket

Backend response is

file:{}

but I'm not sure if $file is empty or it'is just a browser problem, because file should be something like blob.

Can someone helps me? Thanks in advance
