image stored as .tmp in laravel

I am trying to upload an image but when i check my public folder the image has a different name and a .tmp extension :

public function store_company(Request $request)
{
      $request->validate([
          'image' => 'required|image|mimes:jpg,png,jpeg|max:3048'
      ]);

      $name = $request->RS;
      $name = preg_replace('/\s+/', '', $name);

      $NewLogoName = time() . 'lo-go-' . $name . '.' . $request->image->extension();
      $path = $request->image->move(public_path('assets/images' , $NewLogoName));


      $company = new entreprise;

      $company->RS = $request->RS;
      $company->adresse = $request->adresse;
      $company->Fax = $request->Fax;
      $company->Tel1 = $request->Tel1;
      $company->Tel2 = $request->Tel2;
      $company->mail = $request->mail;
      $company->Logo = $NewLogoName;

      $company->save();

      return redirect('/Dashboard');

}   

please any idea how to solve this !

You moved the temporary file (uploaded file) from the tmp folder to the public folder. since you did not provide a name it kept the tmp filename.

in move() the second parameter is the new file name and the first one is just the path.

change it to

$path = $request->image->move(public_path('assets/images'), $NewLogoName);
