Data validator return GET instead of POST

Hi, i'm struggling with a form post request. i'm using laravel 9.45 and php 8.1.12

This is the form file i have text input and a file input

<form method="POST" action="{{ route('update_profile', Auth::user() ) }}">
                    @csrf

This is the web file

Route::put('/{user}/profile/update', 'update')->name('update_profile');

and this is in the controller ( i haven't finished writing this)

    public function update(Request $request, User $user)
    {
        
        $request->validate([
            'name' => ['nullable', 'string', 'max:255'],
            'company' => ['nullable','string', 'max:255'],
            'vat' => ['nullable', 'string', 'max:15'],
            'email' => ['nullable', 'string', 'email', 'max:255', 'unique:users'],
            'avatar' => ['nullable', 'mimes:jpg,png,jpeg', 'max:2048'],
        ]);
        
        dd($request->all());
        $avatar = null;
        if($request->hasFile('avatar')){
           $avatar = $request->file('avatar')->store('/users/avatar', 'public');
        }

        $user->update([
            'name' => $request['name'],
            'company' => $request['company'],
            'vat' => $request['vat'],
            'avatar' => $avatar,
        ]);

        return route('edit', $user);
    }

it works fine but, the request go in the controller and does the thing, BUT only when i try to upload an image the validator method i guess doesn't validate properly and i get this error:

The 1/profile/edit method is not supported for route GET. Supported methods: POST.

and the request:

upload : 302
edit: 405

If i go back to the edit page, the file input displays the error even tho my file is a png image.

i run the cache reset and route cache command, but nothing.

how can i solve this?
