Doesnt Delete From S3

Guys my uploads to s3 work but cannot delete. Can anyone tell me what is the problem is?

    public function deleteStudentFile(Request $request)
    {
        $allowed_guards = ['managers', 'staff', 'students'];

        if (!$this->autherize($allowed_guards))
        {
            response()->json(['error' => 401], 200);
        }
        $this->user = Auth::guard($this->guard)->user();

        $file = StudentAnswerFile::where([
            ['assignment_id', '=', $request->assignment_id],
            ['student_id', '=', $this->user->id]
        ])->first();


        Storage::disk('s3')->delete($file);

        return response()->json(true, 200);
    }

PS. response is true. Thank you in advance.
