axios/laravel/formdata post request is empty

I want to upload some files, but when i post with axios, my formdata is an empty request in laravel

vuejs: uploader.vue

filesChange(e) {
    const fileList = e.target.files;
    const formData = new FormData();
    if (!fileList.length) return;
    for (let i = 0; i < fileList.length; i += 1) {
      console.log(fileList[i]);
      formData.append('files', fileList[i], fileList[i].name);
    }
    this.save(formData);
  },

output from console, all files are looped and appended to formData

save(formData) {
    photosApi.storePhotos(formData, this.galleryId).then((response) =>     {
        console.log(response);
    }).catch((error) => {
        console.log(error);
    });
},

vuejs: photosApi.js

storePhotos(formData, id) {
    return axios.post(`api/photo/${id}`, formData);
},

when i inspect my api-call i see this

laravel: api.php

Route::post('/photo/{id}',  'PhotoController@store');

laravel: PhotoController.php

public function store(Request $request, $id)
{
    return $request->all(); 
}

the return of my response is only empty...

what im'doing wrong?
