Error uploading image in Laravel 9 getClientOriginalExtension() on null

Question

When I upload my image in Laravel 9, I get the following error.

Call to a member function getClientOriginalExtension() on null

Controller

public function upload(Request $request)
{
    $data = new food;
    $image = $request->image;
    $imagename = time().'.'.$image->getClientOriginalExtension();
    $request->image->move('foodimage', $imagename);
    $data->image = $imagename;
}
